Question

Find the exact circumference of a circle with the given radius. 3¼ inches C = 6.25 in. 6.5 in. 23.25 in.

Answer 1

Answer: 6.25π in

Step-by-step explanation:


`\textnormal {Circumference =} 2\pi (3.25) = 6.5 \pi \textnormal{ in}`

Answer 2

Hello!

To find the circumference of a circle you use the equation


`C = 2 \pi r`

C is circumference
r is radius

Put in the values we know


`C = 2 *\pi *3 (1)/(4)`

Multiply the 2 and the 3 1/4


`C = 6.5 \pi`

The answer is
`C = 6.5 \pi`

Hope this helps!
