If the radius (r) is 36 inches, the circumference of the circle is C = 2pi r,
or C = 2pi(36 inches) = 72pi inches. Please note: that's pi, not pie.
Answer:
A
Step-by-step explanation:
pi*r²=616
22×r²=616×7
r²=4312/22
r=14
now
2piR=2×22/7×14
=88
Okay so one side is area is 10x10 or 100 there are 6 sides on a cube, so I can do 6x100 which is 600
