Answer 1

$300 {ft}^{2}$

Step-by-step explanation:

d=20

r=10

π=3

$a = \pi{r}^{2}$

$a = (3) {(10)}^{2}$

$a = 300$

Answer 2

Answer:

A = 300 ft^2

Step-by-step explanation:

First we need to  find the radius

r = 1/2 d

The diameter is 20

r = 1/2(20) = 10

A =pi r^2

We are using 3 for pi

A = 3( 10)^2

A = 3 * 100

A = 300 ft^2
