Question

The diameter of a circle is 15 ft. Find its circumference in terms

Answer 1

Hi!

To find the circumference of a circle, use the following formula:

`\implies\sf{Circumference_o=\pi d}`

• where d is the diameter.

Now, we know that the diameter is 15 ft, so let's plug that into the formula:

`\implies\sf{Circumference_o=15\pi }`

We've found the circumferencce in terms of pi! Cheers :)

Have a nice day!

I hope this helped.

Answer 2

C≈47.25

Explanation:

Use the formula C= πd, where C is circumference, π is pi, and d is diameter.

Input the numbers and we'll shorten π to 3.15

C=3.15(15)

C≈47.25
