Yes, you can.
The circumference of a circle with a diameter of 8 centimeters is = 8*pi cm
The radius is always exactly half of the diameter, so if the radius is 8 cm, then the diameter is 16 cm.
Radius = 1/2 of diameter = 4 cm
Area = 50.265 cm2Circumference = 25.132 cm
Yes, you can.
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.
The circumference of a circle with a diameter of 8 centimeters is = 8*pi cm
Diameter: 2*4 = 8 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
Its circumference is: 8*pi cm
Its circumference is: 8*pi cm
The radius is always exactly half of the diameter, so if the radius is 8 cm, then the diameter is 16 cm.
Radius = 1/2 of diameter = 4 cm
The area of a circle with a diameter of 8 centimeters is: 50.27 square centimeters.
