Question

Find the volume of a cylinder whose radius is 7cm and total surface area is 968cm²​

Answer 1

Answer:

Let height =h

Total surface area=2πr(r+h)

r=7cm

⇒968=2×

7

22

×7(7+h)

⇒

44

968

=7+h

⇒h+7=22

⇒h=22−7

=15cm.

Answer 2

radius r = 7 cm

height h = 22.008854987565 cm

volume V = 0 cm³

lateral surface area L = 968 cm²

top surface area T = 153.9380400259 cm²

base surface area B = 153.9380400259 cm²

total surface area A = 1275.8760800518 cm²
