The diameter of a round dinner plate is 10 inches. What's the area of the plate?

Solution:

Given, the diameter of a round dinner plate is 10 inches.

Radius, r = 10/2 = 5 inches.

We have to find the area of the plate.

Area of plate = πr²

Area = π(5)²

= 25π square units.

Therefore, the area of plate is 25π square units.

Example:

The diameter of a round dinner plate is 10 inches. What's the area of the plate?

Solution:

Given, the diameter of a round dinner plate is 12 inches.

Radius, r = 12/2 = 6 inches.

We have to find the area of the plate.

Area of plate = πr²

Area = π(6)²

= 36π square units.

Therefore, the area of plate is 36π square units.
