1.	Curved surface area of a right circular cylinder is 4.4 m2. If the radius of the base of the cylinder is 0.7 m, find its height.
Answer» Given, Curved surface area of a right circular cylinder = 4.4m² Radius of base of cylinder = 0.7 m =2πrh = 4.4 = h = \(\cfrac{4.4\times7}{2\times22\times0.7}\) = 1 m. ∴ Height of cylinder = 1m.

Curved surface area of a right circular cylinder is 4.4 m2. If the radius of the base of the cylinder is 0.7 m, find its height.

Answer»

Given,

Curved surface area of a right circular cylinder = 4.4m²

Radius of base of cylinder = 0.7 m

=2πrh = 4.4

= h = \(\cfrac{4.4\times7}{2\times22\times0.7}\) = 1 m.

∴ Height of cylinder = 1m.
