Question

if the radius and height of a solid cylinder are 7 cm and 30 cm respectively. then find the volume of the cylinder​

Answer 1

Answer:

Volume of a cylinder = π×r×r×h

V = (22×7×7×30)/7

V = 22×7×30

V = 4,620 cm^3

Answer 2

Given:

Radius of a solid cylinder (r) = 7 cm

Height of a solid cylinder (h) = 30 cm

To find:

Volume of the cylinder = ?

Formula to be used:

Volume of the cylinder (V) =  π$r^{2} h$

Solution:

• The given sum is formula based.
• When we substitute the given values in the standard formula we get the volume.
• The standard value for π is $\frac{22}{7}$ or $3.14$.

Step 1 of 1

Solving for volume of cylinder:

Volume of the cylinder (V) =  π$r^{2} h$

Volume of the cylinder (V) =  $\frac{22}{7}$ × $(7)^{2}$× $30$

Volume of the cylinder (V) = $\frac{22}{7}$ × $49$ × $30$

On simplification, ( 7 times 9 is 49)

Volume of the cylinder (V) = $22$ × $7$ × $30$

Volume of the cylinder (V) = 4620

Final answer:

The volume of the cylinder with 7 cm radius and 30 cm height is $4620cm^{3}$
