Question

The curved surface area of right circular cylinder of base radius 3cm is 94.2 cm^2.The volume of cylinder

Answer 1

2 πx3h=94.2,h=94.2/(2x3.14x3)

= 5cm

volume=πr 2h = 3.14x9x5

141.3cm3

Answer 2

The volume of the cylinder is 141.3 cubic centimeter.

Step-by-step explanation:

Given : The curved surface area of right circular cylinder of base radius 3 cm is 94.2 cm².

To find : The volume of cylinder ?

Solution :

The curved surface area of right circular cylinder is $CSA=2\pi r h$

Radius r=3 cm and CSA=94.2 cm²

Substitute the value in the formula,

$94.2=2\times 3.14\times 3\times h$

$94.2=18.84\times h$

$h=\frac{94.2}{18.84}$

$h= 5\ cm$

The volume of the right circular cylinder is $V=\pi r^2 h$

$V=3.14\times 3^2\times 5$

$V=3.14\times 9\times 5$

$V=141.3\ cm^3$

Therefore, the volume of the cylinder is 141.3 cubic centimeter.
