Question

If the area of a circle measures 16/25 π cm2, what is the circumference of the circle in terms of π? A) 5/8 π cm B) 4/5 π cm C) 8/5 π cm D) 32/50 π cm

Answer 1

C

Explanation:

16

Answer 2

Area=pi*r^2
16/25 therefore is r^2
therefore r=4/5
circumference = 2*pi*r
8*pi/5 is the circumference, C.
