Question

The circumference of a circle equals pi times the diameter. Using 3.14 to approximate pi, what is the approximate circumference in inches of a circle with a diameter of 12 inches? a) 37.68 inches b) 37.68 cm c) 75.36 inches d) 75.36 cm

Answer 1

a

Explanation:

the circumference (C ) of a circle is calculated as

C = πd ( d is the diameter )

given d = 12 inches and using π ≈ 3.14 , then

C = 3.14 × 12 ≈37.68 inches
