What is the area of a circle with a diameter of 8?

Solution:

Given diameter is 8 units

We know that radius of a circle is half of the diameter

So, r = d/2 = 8/2 = 4

The radius of the required circle is 4 units

The circle is a geometrical figure with no edges and an equidistant locus (radius) from the center

We have the formula for the area of the circle with radius r as A = πr²

Area = πr²

= π(4)²

= 16π sq. units

The area of the circle with a diameter of 8 units is 16π sq. units

What is the area of a circle with a diameter of 8?

Summary:

The area of the circle with a diameter of 8 units is 16π sq. units.
