What is the answers if the circle has diameter of 8 what is the area
+5265 The formula for the area of a circle is pi*r2.
The formula for the diameter of a circle is 2r.
First, find the radius.
8/2=4
So, the radius is 4.
pi*4^2 = 50.2654824574366918.
Round to the hundredths.
pi*42≈50.27, so the area of a circle with a diameter of 8 units is approximately 50.27 units2.
