Question

curved surface area of a right circular cylinder is 4.4 metre square if the radius of the base of the cylinder is 0.7 metre find its height​

Answer 1

• The height of the cylinder = 1 m.

Given :–

• Curved surface area of a right circle cylinder = 4.4 m².
• Radius of the base of the cylinder = 0.7m.

To Find :–

• Height of the cylinder.

Solution :–

Given,

Curved surface area of a cylinder = 4.4 m²

$\sf 2\pi rh$ = 4.4 m²

We have,

• r = Radius = 0.7 m.

$\implies 2 \times \dfrac{22}{7} \times 0.7 \: m \times h = 4.4 \: {m}^{2}$

$\implies 2 \times \dfrac{22}{ \cancel7} \times \dfrac{ \cancel7}{10} \: m \times h = \dfrac{44}{10} \: {m}^{2}$

$\implies 2 \times 22 \times \dfrac{1}{10} \: m \times h = \dfrac{44}{10} \: {m}^{2}$

$\implies 2 \times 22 \times \dfrac{1}{ \cancel{10}} \: m \times h \times \cancel{10} = 44 \: {m}^{2}$

$\implies 2 \times 22 \times 1 \: m \times h \times 1 = 44 \: {m}^{2}$

$\implies 2 \times 22 \times h \: \: m = 44 \: {m}^{2}$

$\implies h = \dfrac{44 \: { \cancel{m}}^{2} }{2 \times 22 \: \cancel{m}} \:$

$\implies h = \cancel\dfrac{44}{44} \: m$

$\implies h = \dfrac{1}{1} \: m$

$\implies h = 1 \: m$

Hence,

The height of the cylinder is 1 m.
