Question

the curve surface area of right circular cylinder is 4.4. meter square if the radius of the cylinder 0.7m then height of the cylinder is
​

Answer 1

Answer:

H=1m

Step-by-step explanation:

CSA = 4.4 m^2.

r=0.7 m

CSA of cylinder = 2πrh.

4.4=2πrh.

4.4= 2x22/7x0.7xh.

h=4.4x7/44x0.7.

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

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