Question

a righ circular cylinder of a volume 36.96 cm3 and the radius length of its base is 1.4 cm then find its height (pie = 22 over 7). help pls

Answer 1

Volume of a Cylinder is given by : π × (radius)² × (height)

Given : Radius of the Base = 1.4 cm

Given : Volume of the Cylinder = 36.96 cm³

Substituting the respective values in the Formula, We get :

`\mathsf{\implies \pi * (1.4)^2 * Height = 36.96}`

`\mathsf{\implies (22)/(7) * (1.4)^2 * Height = 36.96}`

`\mathsf{\implies 22 * (0.2) * (1.4) * Height = 36.96}`

`\mathsf{\implies (6.16) * Height = 36.96}`

`\mathsf{\implies Height = (36.96)/(6.16)}`

`\mathsf{\implies Height = 6\;cm}`
