Question
A gardener uses cylindrical roller of diameter 7 cm and
length 28 cm to flatten a rectangular field of dimension 280cm × 165 cm. Find the number of revolutions made by the roller to flatten the entire field?Solution
Let number of revolutions be n. => n × 2π (7/2) × 28 = 280 × 165 => n = 280 × 165 × 1/28 × 1/22 => n = 75
