How do you find the area of a circle that measures the diameter of 8 cm?
The formula for the area of a circle is: A = pi r2 where r is the measure of the radius. If the diameter of a circle is 8 cm, then the radius is half of that measure or 4 cm. Plug that into the formula and use 3.14 to approximate pi. A = 3.14(4)2 A = 3.14(16) Area is approximately 50.24 square cm.
What is the area and circumference of a circle whose diameter is 4 centimeters?

A circle with a radius of 4 cm has an area of 50.27 square cm.
What is the cross sectional area of the 4 pipe?
Method to find area of a circle is: The area of a circle is its radius squared times pi. Assuming the pipe has a diameter of 4cm: radius = 2 cm Circumference = 12.5664 cm Area = 12.5664 cm2
What is a reasonable estimate for the area of a circle with radius 4cm?
area of a circle is pi x radius^2 so... pi x 4^2 = about 50 cm
