Answer:
I think it is 4/9 pi r
Step-by-step explanation:
according to the condition given:
2nd cone has:
Height = 12cm
r= 1/3r (cause it's given 1/3 of radius of the original cone)
We know that volume of a cone is = 1/3 pi (r)^2 h
Now substitute the values:
1/3 * pi* (1/3r)^2 * 12
when u simplify u will get
pi* 1/9*r*4 = 4/9 pi r
So, the answer is probably 4/9 pi r.

Cross multiply,
2x = 8 x 3
2x = 24
x = 24 ÷ 2
x = $12
Use the same principle for the other questions. Use X (or any other variable) to represent the missing value, I e. the value you are calculating.

Answer:
x = 35
Step-by-step explanation:
The figure has 6 angles so the figure is a convex hexagon
The sum of interior angles in a convex hexagon is equal to 720
4x - 5 + 117 + 3x - 3 + 3x + 6 + 118 + 4x -3 = 720 add like terms
14x + 230 = 720 subtract 230 from both sides
14x = 490 divide both sides by 14
x = 35

The value of the c that satisfies the equation is 4(c + 2) = 20. Then the correct option is D.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
The value of c is 3.
F. 2c + 8 = 31
Then we have

Then we have
[tex]32 = 5(7 -3) \\\\32 = 5 (4)\\\\32 \neq 20\\[/tex]

Then we have

What is the zero of
q(x) = -7/3x + 14?
Answer:
x = 6
Step-by-step explanation:
Solve for x:
-(7 x)/3 + 14 = 0
Put each term in -(7 x)/3 + 14 over the common denominator 3: -(7 x)/3 + 14 = -(7 x)/3 + 42/3:
(-(7 x)/3 + 42/3) = 0
-(7 x)/3 + 42/3 = (-7 x + 42)/3:
((-7 x + 42)/3) = 0
Multiply both sides of (-7 x + 42)/3 = 0 by 3:
(3 (-7 x + 42))/3 = 3×0
(3 (-7 x + 42))/3 = 3/3×(-7 x + 42) = -7 x + 42:
(-7 x + 42) = 3×0
0×3 = 0:
-7 x + 42 = 0
Subtract 42 from both sides:
(42 - 42) - 7 x = -42
42 - 42 = 0:
-7 x = -42
Divide both sides of -7 x = -42 by -7:
(-7 x)/(-7) = (-42)/(-7)
(-7)/(-7) = 1:
x = (-42)/(-7)
The gcd of 42 and -7 is 7, so (-42)/(-7) = (-(7×6))/(7 (-1)) = 7/7×(-6)/(-1) = (-6)/(-1):
x = (-6)/(-1)
(-6)/(-1) = (-1)/(-1)×6 = 6:
