Question

The pizza is round and has a radius of 8 inches. Tina only ate 1/3 of the pizza and took home the rest of it. How many square inches of the pizza did Tina eat?

Answer 1

`\approx67\text{ inch}^2`

Explanation:

GIVEN: The pizza is round and has a radius of
`8\text{ inches}`. Tina only ate
`(1)/(3)` of the pizza and took home the rest of it.

TO FIND: How many square inches of the pizza did Tina eat.

SOLUTION:

radius of pizza
`=8\text{ inches}`

Area of circular pizza
`=\pi(\text{radius})^2`

putting values we get,

Area of pizza
`=3.14*8^2=3.14*64`

`=200.96`

Now, Tina only ate
`(1)/(3)` of her pizza

Area of pizza ate by tina
`=(1)/(3)*\text{area of pizza}`

`=(1)/(3)*200.96=66.98`

`\approx67\text{ inches}^2`

Hence tina only ate
`67\text{ inches}^2` of pizza
