Question

Find the volume, lateral surface area and total surface area of a cylinder with radius

7 cm and height 50 cm.​

Answer 1

Answer:

Volume of a cylinder = πr2 h

Lateral surface=2πrh

Total surface area =2πr(h+r)

(i) Base radius = 7 cm; height = 50 cm

Now, we have the following:

Volume=227×7×7×50=7700 cm3

Lateral surface area=2πrh=2×227×7×50=2200 cm2

Total surface area =2πr(h+r)=2×227×7(50+7)= 2508 cm2
