Question : 1 of 40

Marks: +1, -0

Circumference of the base of a cylinder is 88 cm and height of the cylinder is 42 cm. Its volume is

Solution:

Here, 2πr = 88
∴ r =

{88}/{2π}

{88×7}/{2π}

{88×7}/{2×22}

= 14 cm
Since, volume of the cylinder =

πr^2h

{22}/7 × (14)^2

× 42 = 22 × 2 × 14 × 42 = 25872 cu cm.
