Question

the area of a circle of radius r is ​

Answer 1

Answer:

In geometry, the area enclosed by a circle of radius r is πr2. Here the Greek letter π represents the constant ratio of the circumference of any circle to its diameter, approximately equal to 3.14159.

Answer 2

Given : Radius of the circle = r unit

To find : The area of the circle.

Solution :

We can simply solve this mathematical problem by using the following mathematical process.

To solve this mathematical problem, we have to know more about the area.

What is area?

• "Area is the total space occupied by a two dimensional shape."
• Area of different geometrical shapes can be calculated by using different formulas.

Now, there is a dedicated formula to calculate the area of a circle, which is :

Area of a circle = π × (radius)²

Similarity, in this case :

Area of the circle = π × (r)² = πr² sq.units

(This will be considered as the final result.)

Hence, the area of the circle will be πr² sq. units
