Answer: 31.4
Step-by-step explanation:
Circumference = πd or 2πr
π = 3.14
Since the diameter is given we will use Circumference = πd
So
3.14 * 10 = 31.4
Answer:
C ≈ 31.4
Step-by-step explanation:
The circumference of a circle can be calculated using either of the following formulas: C=d or C=2r.
The circumference of a circle is the distance around the outside of the circle. It is like the perimeter of other shapes like squares. You can think of it as the line that defines the shape. For shapes made of straight edges this line is called the perimeter but for circles this defining line is called the circumference.
The radius (r) and the diameter (d) are two more crucial distances on a circle (d). Every circle has three distinguishing features: a radius, a diameter, and a circumference. The circumference may be calculated using the radius or diameter and pi. The diameter of a circle is the distance between one side and the other at its widest points. The circumference of a circle will always pass through its center. This distance is divided in half by the radius. The radius may alternatively be thought of as the distance between the circle's center and its edge.
You can calculate the circumference of a circle if you know its diameter or radius. To begin, keep in mind that pi is an irrational number represented by the symbol. 3.14 is a close approximation.
The formula for calculating a circle's circumference is:
The circumference of a circle is equal to its diameter multiplied by its circumference.
C = d is a common notation for this. This indicates that the circle's circumference is three "and a half" times its diameter.
SOLUTION:Given radius (R) = 5
⇒ Diameter = 2R = 10
⇒ Circumference = 2πR
= 10π
= 31.415926535898
≈ 31. 4

Can you guide me through the steps of finding the area of a circle?
Answer:
A=(3.14)r²
Step-by-step explanation:
First you find your radius if it is a diameter you divide it by 2
Second you multiply the radius by pi (π=3.14)
lastly you square your answer

In your answer, give the volume of the cone rounded to the nearest tenth, and then
explain how you calculated it. (Note: type out all of your work AND type out your
explanation for FULL credit.)
Answer:
39.5 in^3
Step-by-step explanation:
lol someone had the same question
The formula for a cone is (pi)(r^2)(h/3)
Since we have to use 3.14 for pi, we plug 3.14 in for pi:
(3.14)(r^2)(h/3)
The radius is 2 and the height is 8, so we plug in those numbers:
(3.14)(2^2)(8/3)
Simplify:
(3.14)(4)(2.666...)
Multiply:
(12.56)(2.666...) -> 39.49333...
Finally, we round 39.49333... to the tenths place:

Answer:
Total amount of tickets is 48
Step-by-step explanation:
Step 1: Determine the amount of tickets they solid in all
We see that the movie theater has a ratio of 4 adult tickets for every children ticket which means that wen a child purchases a ticket there are 2 adult tickets that come along.
32 adult tickets / (2 adult tickets per child)
16 children tickets
Total tickets: 32 adult tickets + 16 children tickets = 48 tickets
Answer: Total amount of tickets is 48

Given that cos(theta) = 8/17 and that theta lies in Quadrant IV, what is the exact value of sin 2(theta)?
Answer: [tex]-\frac{240}{289}[/tex]
=========================================================
Explanation:
Use the pythagorean trig identity [tex]\sin^2(\theta)+\cos^2(\theta) = 1[/tex] and plug in the fact that [tex]\cos(\theta) = \frac{8}{17}\\\\[/tex]
Isolating sine leads to [tex]\sin(\theta) = -\frac{15}{17}\\\\[/tex]. I'm skipping the steps here, but let me know if you need to see them.
The result is negative because we're in quadrant 4, when y < 0 so it's when sine is negative.
Therefore,
[tex]\sin(2\theta) = 2\sin(\theta)\cos(\theta)\\\\\sin(2\theta) = 2*\left(-\frac{15}{17}\right)*\left(\frac{8}{17}\right)\\\\\sin(2\theta) = -\frac{240}{289}\\\\[/tex]

The farmer needs approximately

According to the question, there are 37000 plants per hectare, the total corn plan required is 475,665.75 corn plants
Determining the area of a trapezium?The trapezium is a 2 -dimensional plane shape with the area calculated as shown below:
The formula for calculating the area of a trapezoid is expressed as:
Area = 0.5(a + b)h
Given the following parameters
a = 500 ftSubstitute the given parameters
Area = 1/2 (500 + 900) * 800
Area = 1/2 (1400) * 800
Area = 560000 square feet
Since 1 acre is equivalent to 43560 square feet, hence the total acre required is expressed as:
Total acre = 560000/43560
Total acre = 12.856 acres
Also since there are 37000 plants per hectare, the total corn plan required is 475,665.75 corn plants
