Question

A circle has a diameter of 10 inches. what is the area of the circle?use 3.14 for pi

Answer 1

The area is 78.54

a=pi(r squared) since the diameter is 10 inches and the radius is 1/2 of the diameter so the radius is 5.

a=3.14(5x5)

a=3.14(25)

a=78.54

Explanation:

Answer 2

The area of a circle with a diameter of 10 inches is 78.5 in².

Explanation:

1. Know the formula for finding the area of a circle.

A = r²
`\pi`

2. Since you need the radius for finding area, you will need to divide 10 by 2 because the radius is half of the diameter.

10 ÷ 2 = 5

3. Add in your numbers to the formula.

A = (5)²
`\pi`

4. Simplify the equation. We can use 3.14 for pi.

A = 25
`\pi`

A = 78.5

So, the area of the circle is 78.5 in².
