Yes, you can.

The circumference of a circle with a diameter of 8 centimeters is = 8*pi cm

Diameter: 2*4 = 8 cm

Its circumference is: 8*pi cm

Its circumference is: 8*pi cm

The circumference of circle that is 8 cm is: about 25.13 cm (diameter x pi = circumference).

Diameter = Radius * 2 In this case, radius = 8 cm so diameter = 16 cm

The area of a circle with a diameter of 8 centimeters is: 50.27 square centimeters.

The area of a circle with a diameter of 8 feet is: 50.27 square feet.

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.

It is 2.5 cm, approx.
