radius of a cylinder is 2 cm and the height is 7 cm its volume is​

Answer 1

Answer:

Answer:

There are two types of natural resources. The first are renewable natural resources. They are called renewable because they can grow again or never run out.

Explanation:

The most popular renewable energy sources currently are:

▪︎Solar energy.

▪︎Wind energy.

▪︎Hydro energy.

▪︎Tidal energy.

▪︎Geothermal energy.

▪︎Biomass energy.

Answer 2

AnswEr :

• The volume of a cylinder = 88 cm².

Explanation :

We are given with the radius of a cylinder as we as height of a cylinder, that is,

• Radius of cylinder, r = 2cm.

• Height of cylinder, h = 7cm.

We have to find out the volume of a cylinder.

We know that, if we are given with the radius of a cylinder and height of a cylinder we have the required formula, that is,

⠀

⠀

→ Volume of cylinder = πr²h.

⠀

⠀

Substituting the given values in the formula,

⇒ Volume of cylinder = 22/7 * (2)² * 7

⇒ Volume of cylinder = 22/7 * 4 * 7

⇒ Volume of cylinder = 22 * 4

⇒ Volume of cylinder = 88

Hence, the volume of a cylinder is 88 cm².

Extra Brainly Knowledge :

Learn some important formulas :

• Volume of cylinder = πr²h.

• TSA of cylinder = 2πrh + 2πr².

• Volume of cuboid = l * b * h.

• CSA of cuboid = 2(l + b)h.

• TSA of cuboid = 2(lb + bh + lh).

• CSA of cube = 4a².

• TSA of cube = 6a².

• Volume of cube = a³.

Where,

• The value of π is 22/7 or 3.14.

• r is the Radius.

• h is the Height.

• l is the Length.

• b is the Breadth.

• a is the Side.
