Question

The volume of a cylinder is 150T cu. cm and its height is 6 cm. Find the areas of its total surface and lateral (curved) surface.​

Answer 1

Answer:

please mark me as brainliest

Step-by-step explanation:

Volume of cylinder =150πcm3

As we know that volume of the cylinder is given as-

V=πr2h

∴πr2h=150π

⇒r2=6150

⇒r=25=5

Therefore,

Lateral surface area =2πrh=2×π×5×6=60πcm2

Total surface area =2πr(r+h)=2×π×5×(5+6)=110πcm2
