Question

Heya Brainly Experts , here's a question :

The radius of a roller is 100 cm and its height is 0.75 m . Calculate the area of land levelled in one rotation of the roller.

APPRECIATION FOR QUALITY ANSWER !​

Answer 1

Answer:

47100cm².

Step-by-step explanation:

Area levelled in one rotation = The Lateral Surface Area of the wheel of the roller.

Area of cylinder = 2πrh.

Therefore,

Area = 2 × 3.14 × 100 × 75 ; (0.75m = 75cm).

Therefore,

Area = 47100cm².

Hence, area of land levelled by the roller in one rotation is 47100cm².

Hope this helped you.

Answer 2

$\huge \sf \red{given}$

$\sf \gray{radius\rightarrow100 \: cm} \\ \sf \gray{height \rightarrow0.75 \: m}$

$\huge \sf \red{to \: find}$

$\sf \gray{the \: area \: of \: land}$

$\huge \sf \red{solution}$

$\sf \gray{let \: learn \: the \: formula \: first} \\ \rm{area \: levelled \: in \: one \: rotation = the \: lateral \: surface \: area \: of \: the \: wheel \: of \: the \: rollar.}$

Area of cylinder=2πRH

       =2×3.14×100×75

       =47100 cm²
