A circular garden has a diameter of 28 m. if a gardener wants to fence 75% of the garden's circumference, what length of fencing is needed? (Use π = 22/7 )
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 66 m.
Radius = 28/2 = 14 m
Circumference = 2πr = 2 × (22/7) × 14 = 88 m
75% of circumference = 0.75 × 88 = 66 m
