Question

The area of circular garden is 706.5 feet2. What is the circumference of the garden? (Use 3.14 for pi .)

Answer 1

30
`\pi` or 94.2 feet

Explanation:

Use the area formula to find the radius:

A =
`\pi`r²

706.5 = 3.14r²

225 = r²

15 = r

Then, find the circumference using the formula:

C = 2
`\pi`r

C = 2
`\pi`(15)

C = 30
`\pi`

So, the circumference of the garden is 30
`\pi` or approximately 94.2 feet
