Question

Curved surface area of a right circular cylinder is 4.4m². If the radius of the base of the

cylinder is 0.7m. Find the height​

Answer 1

$csa \: of \: cylinder = 2\pi rh$

$as \: area = 4.4 {m}^{2} \\ r = 0.7m \\ so$

$4.4 = 2\pi \times 0.7 \times h$

$\frac{44}{10} = 2 \times \frac{22}{7} \times \frac{7}{10} \times h$

$\frac{44}{10 } = \frac{22}{5} \times h$

$h = \frac{44}{10} \times \frac{5}{22}$

$= \frac{2}{10} \times 5$

$= 1$

$therefore \: h \: = 1m$

Let the height of the right circular cylinder be h m.

r=0.7m

Curved surface area = 4.4m²

$\longrightarrow$ 2πrh=4.4

$\longrightarrow$ 2 × $\small\dfrac{22}{7}$ × 0.7 × h = 4.4

$\longrightarrow$ 4.4h = 4.4

$\longrightarrow$ h = 1m

$\small\sf\pink{Hence, \: the \: height \: of the \: right \: circular \: cylinder \: is \: 1m}$
