Question

Find the curved surface area of a cylindrical tank of base radius 30 cm and height 2m

Answer 1

${\pink{\underline{\textsf{\textbf{Answer : }}}}}$

➡️ 37,680m² will be the curved surface area of the cylindrical tank.

${\purple{\underline{\textsf{\textbf{Explanation : }}}}}$

Given that, A cylindrical tank of base radius is 30cm and it's height is 2m or, 200cm

We need to find the curved surface area

We know that,

➩ Curves surface area of a cylinder = 2πrh

r (radius) = 30cm.

h (height) = 200cm.

Therefore,

➩ Curves surface area of a cylinder:

➩ 2 × 3.14 × 30 × 200

➩ 2 × 18,840

➩ 37,680 m² ans.
