47 square inches

Since the answers are spread widely apart, all you need is a very general approximation
diameter is 15 inches, so the radius is 7.5, let's say just 7
𝞹 = 3.14159.... , let's just say 3
area = roughly approximately 3(7^2) < 3*50 = or 150

<b>the closest answer to that is 177</b>

the real answer would be 𝞹(7.5)^2 = 176.71..

The answer is 177 because if you do all the math you will see that that is the answer that is closest to the answer that you originally received.

Work:

Diameter of pizza (d): 15in
15/2=7.5

Radius (r): 7.5

Area (A):

A=r^2π ( Let's just say π=3.14)

r^2=7.5x7.5=56.25

A=56.25x3.14=176.625

176.625 is closest to 177, which makes that the answer. I did this process on a math quiz and I got it correct.
