Question

6. A garden roller is 75 cm in diameter and 105 cm in
width. What area does it cover in 14 revolutions ?​

Answer 1

Answer:

Step-by-step explanation:

d = 75 cm

r = 75/2 cm

width or h = 105 cm

csa = 2πrh

      = 2 × 22/7 × 75/2 × 105

      = 2 × 11/7 × 75 × 15

      = 24750

we got the area covered in 1 revolution is 24750 cm²

area covered in 14 revolutions = 24750 × 14 = 346500 cm²
