Question

The distants around the edge of the pool is 38 feet. What is the area the pool with cover

Answer 1

Answer:

$114.93 ft$

Step-by-step explanation:

$\pi = 3.14$

Given formula to find the area:

$\pi * r^2$

Find radius first:

$Circumference = \pi * 2 * r$

The circumference in this situation would be 38 feet.

$38ft = \pi * 2 * r$

$38 ft = 3.14 * 2 * r$

$3.14 * 2 = 6.28$

$38ft = 6.28 * r$

Since we need to find radius, do division to 38 by 6.28.

$38ft / 6.28 = 6.05$

Our radius is 6.05

Now back to the original formula which is:

$\pi * r^2$

Substitute:

$A = 3.14 * 6.05^2$

$6.05^2 = 36.6$

$A = 3.14 * 36.6$

$==> 114.93ft$
