Question

Find the diameter of the circle with a circumference of 80 feet. Use 3.14 for pi. Round your answer to the nearest tenth.

12.7 ft
25.5 ft
40.0 ft
50.9 ft

Answer 1

Option B = 25.5 ft

Explanation:

Circumference = 80 ft

C = 2πr

80 = 2 * (22/7) * r

80 = (44/ 7) * r

So, Radius (r) = 80 * (7/44)

= 12.72 Feet

--> Diameter = 2r = 2 * 12.72

= 25.45 Feet

Therefore, Answer = Option B = 25.5 Feet (Round off)
