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

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

Answer 2

Answer:

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}

22

× 0.7 × h = 4.4

\longrightarrow⟶ 4.4h = 4.4

\longrightarrow⟶ h = 1m
