# Chapter 9 - Section 9.3 - Area, Volume, and Surface Area - Exercise Set: 26

$A=2.5^2\pi=6.25\pi\approx 6.25\times\frac{22}{7}\approx19.643$ square m.

#### Work Step by Step

The area of the circle can be calculated as: $A=r^2\pi$ where r is the radius. Here: $d=5$ m $r=2.5$ m $A=2.5^2\pi=6.25\pi\approx 6.25\times\frac{22}{7}\approx19.643$ square m.
