Two formulas here:
Area = πr²
Circumference = 2<span>πr
So first we solve for r from area:
25</span>π = πr²
25 = r²
r = 5
So we know that radius is 5 cm.
Now substitute r to 5 in circumference formula:
C = 2π(5) = 10π
Final answer: 10π cm
Hope this helps.

Answer:
6 minutes
Step-by-step explanation:
There are 60 minutes in an hour. This can be broken up into 5 12-minute intervals. From there, you can do 3 intervals of 12 minutes which is 36 minutes. The 36 minutes is divisible by 6 questions getting to 6 minutes per question.
