Question

Patrick’s Pizza Parlor is famous for its giant circular pizza, which has an area of 1,519.76 square inches. Approximately what is the diameter of the giant pizza?

Answer 1

Explanation:

the diameter of a circle is 2 times the radius.

the area of a circle is

pi × r²

r being the radius.

so,

1519.76 = pi × r²

r² = 1519.76/pi = 483.7546326...

r = 21.99442276... in

diameter = 2r = 43.98884552... in ≈ 44 in
