# Curved surface area of right circular cylinder is 4.4 m square if the radius of the base of the cylinder is 0.7 metre find its heightâ€‹

Given that

Curved surface area of right Circular Cylinder = 4.4 m

we need to find height

Curved surface area of right circular cylinder = 2πrh

\begin{aligned} &\Rightarrow 4.4=2 \times \frac{22}{7} \times 0.7 \times h\\ &\Rightarrow 4.4=2 \times \frac{22}{7} \times \frac{7}{10} \times h\\ &\Rightarrow 4.4=2 \times \frac{22}{7} \times \frac{7}{10} \times h\\ &\Rightarrow 4.4=\frac{44}{10} h\\ &\Rightarrow 4.4 \times 10=44 h\\ &\Rightarrow \frac{44}{10} \times 10=44 h\\ &\Rightarrow h=\frac{44}{44}\\ &\Rightarrow h=1 \end{aligned}
