My Question is a simple Question.

Question

How do you find the circumference and area of a circle with a radius of 12.

Answer 1

C = 2πr

Plug in r, which you know.

A = πr²

Again, plug in r, which you know.

Answer 2

Hello Emme!

Emme, you can find the circumference of a circle using the formula for circumference which is C=2(pi)r.

1) Plug in your values for the formula.

C=2(pi)r

C=2(3.14)(12)

C= 75.36 or 24pi

For the area, you can use the area of circle formula which is A=(pi)r^2

Again, plug in the given values that the problem has given you. Plug those numbers into the formula to get your answer.

A=(pi)r^2

A=(3.14)(12)^2

A= 452.16

I hope this helps you out, Emme! Please reach out to me if you are still confused about this problem.
