Answer 2

Answer:

$\boxed {\boxed {\sf a \approx 113.0 \ ft^2}}$

Step-by-step explanation:

The area of a circle is the space inside the shape. The formula is:

$a= \pi r^2$

We know the radius of the circle is 6 feet and we are using 3.14 for pi.

• r= 6 ft
• π= 3.14

Substitute the values into the formula.

$a= (3.14) \times (6 \ ft)^2$

Solve the exponent.

• (6 ft)² = 6 ft * 6 ft = 36 ft²

$a= (3.14) \times 36 \ ft^2$

Multiply.

$a=113.04 \ ft^2$

Let's round to the nearest tenth. The 4 in the hundredth place tells us to leave the 0 in the tenths place.

$a \approx 113.0 \ ft^2$

The area of the circle is approximately 113.0 square feet.
