Answer 1

Answer:

38.47 feet²

Step-by-step explanation:

To get a radius, you need to divide the diameter into two.

7 ÷ 2 = 3.5

π r² is the equation for the area of a circle.

3.14 × 3.5²

3.14 × 12.25

3.14 × 12.25 = 38.465

After rounding your answer to the nearest hundredth,

38.47 feet²

Answer 2

The area of the mat should be $38.47 feet^2$

Given information:

The diameter of one of the circular mats is 7 feet.

Calculation of the area:

Since the diameter is 7 so the radius should be half i.e. 3.5

Now the area should be

$=\pi r^2\\\\ =3.14 \times 3.5^2\\\\=3.14 \times 12.25\\\\= 38.47 feet^2$
