Area of a circle
The formula for calculating the area of a circle is expressed as shown below;
A = πr²
where
r is the radius of the circle
Given the following parameters
diameter = 10.2
radius = 10.2/2 = 5.1
Substitute
Area = 3.14(5.1)²
Area = 81.6714
Hence the area of the circle to the nearest tenth is 81.7 square units to the nearest tenth
