Question

The radius of a circle is 8 feet. What is the circle's area?
Use 3.14 for ​.

Answer 1

200.96 ft²

Explanation:

Step 1: Define/formula

To find the area of a circle, multiply the radius by itself twice, then multiply the product by pi.

`a=\pi r^2(3.14*radius*radius)`

Step 2: Solve

According to the word problem, the radius is 8.

From here, we plug the numbers into the formula.

`\pi 8^2(3.14*8*8)=200.96ft^2.`

Step 3: Conclude

Therefore, the area of this circle is 200.96 ft.²

Answer 2

50.27

Explanation:

remember that the circumference of a circle is 2πr

so 3.15x8 and then multiply by two
