Question

5) A cylinder of height 10cm and the area of it's base is 154 cm. then the volume of
the cylinder is​

Answer 1

Answer:

The volume of the cylinder is 1540 cm³.

Step-by-step explanation:

The volume of a cylinder is,

$Volume=\pi r^{2}h$

Given:

height (h) = 10 cm

Area of circular base = 154 cm².

That is,

$Area=\pi r^{2}=154$

Compute the volume as follows:

$Volume=\pi r^{2}h=154\times 10=1540$

Thus, the volume of the cylinder is 1540 cm³.

Answer 2

h = 10 cm

area of base = 154 cm²

so,

πr² = 154

r² = 154/π

r² = 154/22/7 ( let, π = 22/7 )

r² = 154 × 7 / 22

r² = 7 × 7

r = 7 cm

We know,

Volume of cylinder = πr²h

=> V = 22/7 × 10 × 7 × 7

=> V = 22 × 70

=> 1540 cm³
