Question

A circle has a circumference of 59 cm

Using 3.14 as an approximation for π, what is the approximate value for the radius of of the circle

A 4.7 cm
B 9.4 cm
C 18.8 cm
D 37.6 cm

Answer 1

B 9,4 cm

Explanation:

The circumference of a circle is:

2πR

We know that the circumference of this circle is 59 cm, therefore, we can calculate your radio:

2πR = 59

2(3,14)R = 59

6,28 R = 59

R = 59/6,28

R = 9,394....

R ≈ 9,4
