..QUESTION..

A roller of HEIGHT 10 m and radius 0.35 m is USED to level a lawn . Find the area ( in sq. m ) it can level in one full rotation.

..ANSWER..

Given ,

ㅤㅤㅤ➪ height of roller = 10 m

ㅤㅤㅤ➪ Radius of roller = 0.35 m

★ Hint* - The role is a cylinder

•°• To find the area leveled in 1 rotation

ㅤㅤ➪ we are to find it's C.S.A

•°• According to the Question ,

ㅤㅤㅤ➪ C.S.A of cylinder

ㅤㅤㅤ➪ 2 π r h

ㅤㅤㅤ➪ 2 × 22/7 × 0.35 × 10

ㅤㅤㅤ➪ 44/7 × 3.5

ㅤㅤㅤ➪ 44 × 0.5

ㅤㅤㅤ➪ 22

•°• area leveled in 1 rotation ➪ 22 m²
