Question

The diameter of a garden cylindrical roller is 2.8 m long . How much area will it cover in 100 revolutions

Answer 1

Answer: 616 sq. m

Step-by-step explanation:

d = 2.8m, r= d/2, A=pi r^2

r = 2.8/2 = 1.4m

Area, 1 revolution = 22/7 x 1.4 x 1.4

A = 6.16 sq. m

1 rev. = 6.16 sq. m

100 rev. = (6.16 x 100)/1

= 616 sq. m
