# Curved surface area of a right circular cylinder is 4.4 $${m}^2$$. If the radius of the base of the cylinder is 0.7 m, find its height.

Given :
Radius (r) of the base of cylinder = 0.7 m
CSA Of cylinder = 4.4 $${m}^2$$

Let the height of the circular cylinder be h.

Therefore, we have,

$$\Rightarrow$$ $$2{\pi}rh$$ = 4.4 $${m}^2$$
$$\Rightarrow$$ $$2 × \frac{22}{7} × 0.7 × h$$ m = 4.4 $${m}^2$$
$$\Rightarrow$$ $$2 × 22 × 0.1 × h$$ m = 4.4 $${m}^2$$
$$\Rightarrow$$ h = 1 m.

Therefore, the height of the cylinder is 1 m.
