Question : 11 of 120

Marks: +1, -0

The volume (in. cu.cm) of the right circular cylinder with radius I cm and height 2 cm is Take π =

22/ 7

Solution:

(4)

\ { r } = 1 { cm } , { h } = 2 { cm }

Volume of Cylinder

= π { r } ^ { 2 } { h }

= π ( 1 ) ^ { 2 } ( 2 )

= { 22 }/ { 7 } × 1 ×2 = { 44 }/ { 7 } { cu } . { cm } . [ ∴ π = { 22 } /{ 7 } \right]
