A circular dance stage has an area of 256π square feet. What is the circumference of the stage rounded to the nearest hundredth? A-804.25 B-402.12 C-100.53 D-50.27

Answer 1

256pi = pi(r)^2

r^2 = 256

r = sqr256 = 16 feet

circumference = 2pi(r) = 2pi(16) = 32pi= about 32(3.14159) = 100.53 feet

C) is correct
