Question

Curved surface area of a right circular cylinder is 35.2m2. If the
radius of the base of
the cylinder is 2.8m, find its height.​

Answer 1

Answer:

The height of the right circular cylinder is 2 metre.

Step-by-step explanation:

According to the problem,

curved surface area of a cylinder = 2πr * h

or, 35.2 = 2* 22/7 * 2.8* h

or,

$\frac{352}{10} = \frac{2 \times 22 \times 28}{7 \times 10}h \\ = > 352 = 2 \times 22 \times 4 \times h \\ = > \frac{352}{8 \times 22} = h \\ = > 2 = h$

thus, h = 2 metre

r = radius of the base

h = height of the cylinder
