Question

The lateral surface area of a cylinder is 1056cm square and its height is 16 cm . Find it's volume.​

Answer 1

Answer:

5,544 cm³

Step-by-step explanation:

Lateral surface area of cylinder = 2πrh = 1056 cm²

h = 16 cm

r = lateral surface area / 2πh

r = 1056/(2×3.14×16) = 10.5cm

Hence r = 10.5 cm

Volume = πr²h = 3.14×10.5²×16 = 5,544 cm³

Answer 2

Answer:

5544 cm²

Step-by-step explanation:

lateral surface area of a cylinder=2πrh

1056=2πrh

1056=2×22/7×r×16

1056×7/2×22+16=r

21/2=r

Volume=πr²h

=22/7×21/2×21/2×16

=5544 cm²

hope this helps you...
