Answer:

The area of 1 slice is of 19 square inches.

Explanation:

Area of a circle:

The area of a circle of radius r is given by:

$A = \pi r^2$

A large pizza has a radius of 7 in.

So its area of the pizza, in square inches, is of:

$A = \pi(7)^2 = 49\pi = 49*3.14 = 153.86$

The pizza is cut into 8 slices of equal size. What is the area of 1 slice, rounded to the nearest whole number?

Area of the pizza divided by 8. So

153.86/8 = 19.2

Rounding to the nearest whole number, the area of 1 slice is of 19 square inches.
