Question

The curved surface area of a right circular cylinder of base radius 3cm is 94.2cm^2.The volume (in cm^3) of the cylinder is ?(take pi = 3.14)​

Answer 1

Answer:

141.3 cm³

Step-by-step explanation:

Curved Surface Area  a right circular cylinder  = 2πrh

2πrh  = 94.2

=> 2π * 3 * h = 94.2

=> h = 15.7/π

Volume OF Cylinder = πr²h

=  π (3)² * (15.7/π)

= 9 * 15.7

= 141.3 cm³

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.
