Question

Question The Curved surface area of a right circular cylinder is 4.4 sq.cm. The radius of the base is 0.7 cm. The height of cylinder will be​

Answer 1

Answer:

Answer. according to the question, CSA of the cylinder is 4.4m² and radius of it's base is 0.7m. hence, the height of the cylinder is 1m.

Step-by-step explanation:

Answer 2

The height of the cylinder is 1cm.

Given: Right circular cylinder

Curved surface area = 4.4 cm²

Radius of the base = 0.7cm

To Find: The height of the cylinder

Solution:

The curved surface area of a cylinder is given as

CSA = 2πrh, where CSA is the curved surface area, r is the radius of the cylinder and h is the height of the cylinder.

On placing the given values in the formula, we get

4.4 = 2π (0.7)(h)

4.4 = 2 x $\frac{22}{7}$ x 0.7 x h                            π = 22/7

44 = 2 x 22 x h

h = 1 cm

Therefore, the height of the cylinder is 1cm.
