A circular pizza has a diameter of 16 inches. Each slice of pizza has a central angle of 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

Answer :

Answer:

C.

Step-by-step explanation:

Radius = 16 ÷ 2 = 8

[tex]\frac{45}{360} *8^2*\pi =25.1[/tex] (3sf)

You can first find the total area of the circle which is [tex]64\pi[/tex].

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 [tex]\frac{180}{360} *8*\pi[/tex].
