Question

A large pizza from domino’s has a diameter of 16 in. Suppose the pizza is a perfect circle cut into 10 equal slices. If Jason eats 3 slices how much did he eat in square inches

Answer 1

About 60.32 sq. in.

Explanation:

Diameter = 16

Radius is half of diameter, so radius is:

Radius = 16/2 = 8

r = 8

Jason ate 3 out of 10 slices. How much did he eat?

We will find the area of the pizza in square inches and then find (3/10)th of it to find portion Jason ate.

Area of Pizza (circle):

`A=\pi r^2\\A=\pi (8)^2\\A=64\pi`

Now, find (3/10) of it:

`Ate=(3)/(10)*64\pi\\Ate=19.2\pi\\Ate=60.32`

Jason ate about 60.32 square inches of pizza
