Question

Please help me ASAP!!!
A circular pizza has a diameter of 16 inches. Each slice of pizza has a central of angle 45°. What is the area of each slice of pizza?

A. 3.1 in²
B. 6.13 in²
C.25.1 in²
D. 100.5 in²

I know that the area is 8π² I just don't know which answer choice it is.

Answer 1

Answer:

C.

Step-by-step explanation:

Radius = 16 ÷ 2 = 8

$\frac{45}{360} *8^2*\pi =25.1$ (3sf)

You can first find the total area of the circle which is $64\pi$.

Then, you can find the area of the slice of the pizza, if you take the ratio of the angle it creates with the total angle of a circle (360.)

For example, a semicircle's are would be  $\frac{180}{360} *8*\pi$.

Answer 2

Answer:

C. 25.1 in²
