Please Help !! What is the surface area of a cylinder with base radius 4 and height 5. Show your work .
Answers
Answer:
226.19
Step-by-step explanation:
A= 2πrh+ 2πr2= 2·π·4·5+2·π·42≈226.19467
or
S = (2 * pi * r^2) + (2 * pi * r * h)
S = (2 * pi * 4^2) + (2 * pi * 4 * 5)
S = (32 pi) + (40 pi) = 72pi = 226.08 ANS.

But you may use the protacter to find the angle
? = 73°
There are 7 sides in this polygon
Calculate total interior angles using (n-2) * 180
["n" denotes number of sides]
Here total interior angle: (7-2)*180 = 900°The missing angle inside the polygon:
900° - 130° -119° -130° -154° -130° -130°
900° - 793°
107°
A straight line has total 180°
? + 107° = 180°
? = 180° - 107°
? = 73°

Answer:
X = 42
Step-by-step explanation:
Think of this problem as a division problem.

Answers
The value a = -1 < 0 represents the translation -1 units to the left and
b = 9 > 0 represents the translation 9 units up is correct.
The rule of transformation is defined as,
( x , y ) → ( x + a , y + b ) (equation - 1)
Where, a is horizontal shift and b is vertical shift.
If a>0, then the graph shifts a units right and if a<0, then the graph shifts a units left.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
Based on the given conditions, formulate,
(x, y) → (x-1, y+9) (equation - 2)
From (1) and (2) equations,
We get,
a = -1 , b = 9
The value a = -1 < 0 represents the translation -1 units to the left and
b = 9 > 0 represents the translation 9 units up.
Therefore,
Description of the rule is,
The value a = -1 < 0 represents the translation -1 units to the left and
b = 9 > 0 represents the translation 9 units up is correct.

20) What fraction of the square is shaded if the line inside divides the square into two equal parts?
please help me fast please
Answers
Answer:
3/8 of the area is shaded
Step-by-step explanation:
this can be determined by deviding the total shape into parts and determining those parts
so we see the top right 1/4 of the shape has a square that is shaded, with the triangle only covering 1/2 of this shape becuase the hypotenuse ((diagnal edge of a right triangle)) devides the square in half
beings that 1/2 of the 1/4 square is shaded, we know that in reation to the whole shape that the small shaded area is equal to 1/8 ((1/2 ÷ 1/4 = 1/8))
same can be said for the bottum shape, with the bottum half of the whole shape half covered we can determine its total shaded area in relation to the shape ((1/2 ÷ 1/2 = 1/4))
the left top shape is completely unshaded so we wont need to calculate any shadded area into the equation
with the total shape covered by 1/4 + 1/8 we can find the least common denominator between the two fractions to get a simplifide answer for the total shaded area
1/4 = 2/8
2/8 + 1/8 = 3/8
this leaves 5/8 of the shape unshaded
3/8 fraction of the square is to be shaded.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
In the top right 1/4 of the shape has a square that is shaded, with the triangle only covering 1/2 of this shape because the hypotenuse divides the square in half.
1/2 of the 1/4 square is shaded, we know that in relation to the whole shape that the small shaded area is equal to 1/8.
same can be said for the bottom shape, with the bottom half of the whole shape half covered we can determine its total shaded area in relation to the shape.
1/4 = 2/8
2/8 + 1/8 = 3/8
Hence, 3/8 fraction of the square is to be shaded.

A store buys a remote control robot for $60. They mark it up by 30%. What will be the selling price
Answers
Step-by-step explanation:
The store buys a remote control robot for $60 plus it marks up by 30%.
First, we need to convert 30% to a decimal of 0.30.
Then we multiply 60 by 0.30.
60*0.30=18
We know we have to add the original price of $60 with an $18 markup.
60+18=78
We now get $78 as the selling price.

Answers
sum of three number= 98
to find:the second number.
solution:Let the three numbers be x, y and z
Sum of the numbers is 98.
x + y + z = 98………………(i)
The ratio of the first to the second is 2/3.
x/y = 2/3
x= 2/3 × y
x= 2y/3
The ratio of the second to the third is 5/8.
y/z= 5/8
z/y= 8/5
z= 8/5 × y
z= 8y/5
Put the value of x = 2y/3 and z = 8y/5 in (i).
2y/3 + y + 8y/5= 98
49y/15= 98
49y= 98 × 15
49y= 1470
y= 1470/49
y= 30
Therefore, the second number is 30.

He should make a loan from the investors about 4.6%..
What is Percentage?To determine the volume or chance of commodity in terms of 100, use the chance formula. Per cent simply means one in a hundred. With the chance formula, a number between 0 and 1 can be expressed. A number that's expressed as a bit of 100 is what it is. It's substantially used to compare and determine rates and is represented by the symbol.
Total quantum plutocrat Korey have
= Saving plutocrat heritage plutocrat
= $,500$,000
= $,500
Total quantum of charges
= Store Fixtures amount + Computer and Cash Register amount + Inventory amount +Rent amount + Insurance amount
= $2700 + $1200 + $17400 +$10800 + $3000
= $35100
So, Fund taken through loans and investor
= Total quantum of charges -Total quantum plutocrat Korey have
= $ 35100-$ 33500
= $ 1600
and, the percentage is
= 1600 x 100 / 35100
= 4.6%
He should make a loan from the investors about 4.6%.
