Answer:

Step-by-step explanation:
The given equation is A=4 πr².
We need to solve the above equation for r².
We have,
A=4πr²
Dividing both sides by 4π, we get :

Hence, the value of r² is equal to
.
Answer:
6.687898089 = r
Step-by-step explanation:
#3 Circumference is given by
C = 2 * pi *r
We know the circumference is 42
42 = 2 * pi *r
Divide each side by 2 pi
42/2pi = 2pir/ 2pi
21/pi = r
Approximating pi by 3.14
21/3.14 = r
6.687898089 = r
