Question

Find the volume and total surface area of a cylinder whose ra-

dius of the base is 21 cm ad height is 50 cm.​

Answer 1

Step-by-step explanation:

• Here, Radius = 21 cm
• Height = 50 cm
• So, Volume of cylinder = πr^2h = 22/7*21*21*50 = 22*3*21*50 = 69300 cm^3
• Now, Total surface area of cylinder = 2πr(r+h) = 2*22/7*21(21+50) = 44*3*71 = 9372 cm^2

Answer 2

Answer:

Total surface area:

=2πr(h+r)

=2×22/7×21(50+21)

=9,372cm²

Volume:

=πr²h

=22/7×21×21×50

=69,300cm²
