Question

Find the curved surface area of a garden roller whose length and diameter are 1.5 m and 1.4 m respectively. How much area can it level in 200 revolutions?​

Answer 1

Step-by-step explanation:

radius of garden roller = 1.4/2 = 0.7

height = 1.5

c. s. a of a cylinder =

$2\pi \: rh$

c. s. a of garden roller = 2 x 22/7 x 0.7 x 1.5

= 6.6

area it can level in 200 revolutions = 200 x 6.6

= 1320
