Question

Martin ordered a pizza with a 16-inch diameter. Ricky ordered a pizza with a 20-inch diameter. What is the approximate difference in area of the two pizzas?

ANSWER FAST

Answer 1

the difference in diamante r is it is 4 inches bigger than the 16 inch.

Explanation:

Answer 2

The difference in area of the two pizzas is 113.14 inch².

Explanation:

Martin ordered a pizza with a 16 inch diameter and Ricky ordered a pizza with a 20 inch diameter.

We have to calculate the approximate difference in area of the two pizzas.

Ara of pizza ordered by Martin =
`\pi r^(2)`

=
`\pi ((16)/(2) )^(2) =\pi 8^(2) =64\pi`

Area of pizza ordered by Ricky =
`\pi ((20)/(2))^(2) =\pi 10^(2) =100\pi`

Difference in area =
`100\pi -64\pi`

=
`(36\pi )`

= 113.14 inch²

The difference in area of the two pizzas is 113.14 inch².
