How do you find the area of a circle in terms of pi?

Question

I know how u find the area I just need help with this. It says to find the area in terms of pi. Do you find the answer and leave pi or multiply ur answer by pi? Ie. A circle with a radius of 6in. Is the answer 36pi or 36*3.14?

Answer 1

Leave the pie!

36 pies is the correct answer.

Pies!

Answer 2

You're fine if you are supposed to leave your answer in terms of pi.  The are of a circle with radius of 6 inches is:

A = (pi)*r^2

A = (pi) *6^2

A = 36(pi)

I am using (pi) to represent the symbol.

Answer 3

It's 36 with the pi symbol

Answer 4

to find the area of a circle you do

Area = (pi)*radius^2 (pi times radius squared)

So Area = app 3.14159 times (6 times 6)

So Area = app. 3.14159 times 36

So area of circle with 6 inch diameter = app. 113.09724 inches squared!

Or 36 times pi (app 3.14159)

Or 36(pi)
