Question

results for a dvd has a radius of 12cm. what is the diameter and circumference of the dvd? round to the nearest hundredth

Answer 1

Diameter: 24 Circumference: 75.36

Explanation:

(equation for finding circumference: 2(3.14)r or 3.14d)

2(3.14) x 12 = approximately 75 or 75.36

Diameter = r2

12(2) = 24

Answer 2

C = 2πr
C = 2 x π x 12
C = 24π
C = 75.39822
