Question

The volume of right circular cylinder of height 14 cm is 1100cm cube . find the radius of the base of the cylinder
plz answer soon​

Answer 1

Given:

• The volume of right circular cylinder = 1100 cm³

• Height of right circular cylinder,h = 14 cm

To find out:

Find the radius of the base of the cylinder.

Formula used:

Volume of cylinder = r²h

Solution:

Volume of cylinder = r²h

→ 1100 = 22/7 × r² × 14

→ 1100 = 22 × r² × 2

→ 1100 = 44 × r²

→ r² = 1100/44

→ r² = 25

→ r = 5 cm

Hence, The radius of the base of the cylinder is 5 cm.

Answer 2

Given :

• The volume of right circular cylinder = 1100 cm³

• The height of right circular cylinder = 14 cm

To find :

• Radius of right circular cylinder =?

Step-by-step explanation:

The volume of right circular cylinder of height 14 cm is 1100cm cube . [Given]

We know that,

The volume of right circular cylinder = πr²h

Substituting the values in the above formula, we get,

➮ 1100 = (22/7) r² × 14

➮ 1100 = 22 × r² × 2

➮ 1100 = 44r²

➮ r² = 1100/44

➮ r² = 25

➮ r = √25

➮ r = 5

Therefore, Radius of right circular cylinder = 5.

Properties of Right Circular Cylinder

Properties of Right Circular CylinderYou must have learned about the properties of the cylinder before.

Here, let us discuss the right circular cylinder properties.

• The line joining the centres of the circle is called axis.

• When we revolve a rectangle about one side as the axis of revolution, a right cylinder is formed.

• The section obtained on cutting a right circular cylinder by a plane, which contains two elements and parallels to the axis of the cylinder is the rectangle.

• If a plane cuts the right cylinder horizontally parallel to the bases, then its a circle.
