Answer:

Diameter of pizza = 14 inches

Explanation:

Pizza is shaped like a circle

If the radius of the pizza is r, the area which is the area of a circle of radius r is given by

$A = \pi r^2$

Here we are given the area as 153.86 in²

153.86 = π · r²

r² = 153.86 /π

r = √( 153.86 /π )

= 6.998 in

≈ 7 inches

Diameter = 2 x radius

= 14 inches
