Question

If the diameter of the base of a cylinder is 7cm and volume is 577.7 cm cube .Find the height of the cylinder​

Answer 1

Step-by-step explanation:

radius of the base = 7/2 = 3.5 cm

Volume = πr²h

577.7 = 22/7 × 7/2 × 7/2 × h

h = 577.7×7×2×2 / 22×7×7

h = 577.7×4 / 22×7

h = 5777×4 / 22×70

h = 5,777×2 / 77×10

h = 11554 / 77×10

h = 150.05 / 10

h = 15.005 cm = 15 cm
