What is the area of a circle with a radius of 4 units?
The area of a circle is the amount of space enclosed within the boundary of a circle.
Answer: The area of the circle with a radius of 4 units is 16π sq. units.
Let's find the area of the circle.
Area of a Circle = πr2 = πd2/4
- where r is the radius of the circle
- where d is the diameter of the circle.
- π is the constant whose value is approximately 22/7 or 3.14...
So, the area of circle = πr2
Given that radius of the circle is 4 units.
Then the area of circle = πr2 = π(4)2 = 16π square units.
