Area = r^2 x PI
to find r take the square root of the area:
r = √100 = 10
The circumference of a circle is the diameter times PI.
The diameter is 2 times r = 2 x 10 = 20
The circumference = 20PI m
The answer is C.
A copy machine makes 36 copies in a minute (1).
Multiply 36 copies by 3.75 (3 min and 45 sec) to find how many copies it can make within that time.
(36)(3.75) = 135
The copy machine can make 135 copies in 3 minutes and 45 seconds.
