Question

2m long road roller covet 17.6 m distance during one revolution. Find its curved surface area.​

Answer 1

Step-by-step explanation:

When a body covers equal distances in equal intervals of time, however small the intervals may be, the body is said to be moving with uniform speed. When a body covers unequal distances in equal intervals of time, the body is said to be moving with variable speed or non-uniform Speed.

Answer 2

Step-by-step explanation:

$given \: roller \: is \: in \: the \: form \: of \: cylinder$

$hence \\➵ \: height \: of \: roller = 2m \\ ➵ \: distance \: cover \: by \: roller \: in \\ \: 1 \: revolution = 17.6m \\➵ diameter \: of \: roller = 17.6m \\ radius = 8.8m$

➶To find:- CSA

$csa = 2\pi \times rh \\ ➵ \: 2 \times \frac{22}{7} \times 8.8 \times 2 \\ \frac{44}{7} \times 17.6 \\ ➵ \: \frac{774.4}{7} \\ ➵ \: 110.628 \: m$

➶Hence, CSA of roller = 110.628m
