Answer:

5. R = 6

6. D = 22

Step-by-step explanation:

5. The area formula is πr2.

If πr2=36π,

π can be canceled out from both sides.

Then, it is r2=36.

If we square root both sides, we get:

r=6 .

Therefore, the radius of your circle is 6.

6.A = 121 π

A = r² π

r² π = 121 π

r = √ 121 = 11

The diameter: d = 2 r = 2 * 11 = 22 units
