Question

curved surface area of a cylinder is 4.4 CM square the radius of the base of the cylinder is 0.7 cm find itscurved surface area of a cylinder is 4.4 CM square the radius of the base of the cylinder is 0.7 cm find its side​

Answer 1

Answer:

$\huge\mathfrak\red{ANSWER}$

Curved surface area of cylinder

= 2πrh

4.4= 2×22/7 ×0.7×h

4.4=4.4h

h= 1 cm✔

Answer 2

Solution :

Height of the cylinder be 'h'.

Given:

Radius of the base of cylinder (r) = 0.7 cm

C. S. A. (cylinder) = 4.4 cm²    

As we know that:

$\implies$ $\boxed{\sf{C.\:S.\:A.\:of\:cylinder = 2\pi r h}}$

So, we get:

$\implies$ 2πrh = 4.4 cm²

$\implies$ 2 × 22/7 × 0.7 × h = 4.4

$\implies$ h = 4.4/4.4

$\implies$ h = 1 cm

Hence,

The height of the cylinder is 1 cm.
