A 70cm wide path is made around a circular garden having a diameter of 14 metres. What is the area of the path (in m2)?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 10.29π.
Diameter of garden = 14 m → Radius = 7 m
Width of path = 70 cm = 0.7 m
Outer radius (including path) = 7 + 0.7 = 7.7m
Area of path = Area of outer circle − Area of inner circle
= π(7.72 − 72) = π(59.29 − 49) = π × 10.29 = 10.29π m2
