Question

Sven drew a circle with a circumference of about 75.36 centimeters. What is the approximate

length of the radius of Sven's circle?
A. 6 cm
B. 12 cm
C. 24 cm
D. 25 cm​

Answer 1

circumference = 2pi(r) (r being radius)

75.36 = 2pi(r)
75.36 = 2(3.14)(r)
75.36 = 6.28 (r)

divide both sides by 6.28 to leave R on one side.

75.36/6.28 = 6.28r/6.28

12cm = r

Answer 2

12 cm

Explanation:

75.36/pi=approximately 23.9, rounded, that is 24, divided by 2 is 12
