Area = pi*r^2
Circumference = 2pi*r
Step 1: find the radius from area
81pi=pi*r^2
81=r^2
9=r
Step 2: plug in radius to the circumference equation
Circumference = 2pi*r
18pi is the answer, otherwise know as 56.52 as well.
Answer:
41.6 lol
Step-by-step explanation:
A
Step-by-step explanation:
I do now know what this is about
79.57 times 12% = 70.02
