pi*r2 = 28.26 Divide both sides by pi: r2 = 8.995437384 Square root both sides: radius = 2.999239468 diameter = 2*radius: diameter = 5.998478935 or 6 centimeters to the nearest cm.
The area of a circle with a diameter of 6.4 centimeters is: 32.17 cm2
16 centimeters.
201.06 square centimeters.
If the circumference of a circle is 45 cm the length of the diameter in centimeters is: about 14.32 cm
The circumference of a circle with a diameter of 6 centimeters is 18.85 centimeters.
60 millimetres
Diameter is 6 cm
If the diameter is 12 cm the radius is 6 cm.
d = 1.91cm
The volume is about 1231.5 cube centimetres.
It is: diameter/2 = 6 cm
The radius of a circle is half the length of the diameter, so if the diameter is 32 centimeters the radius is 16 centimeters.
the area of a circle is pi times the radius squared. The diameter is 12, so the radius is 6 (half of the diameter). Therefore, the area is pi times 6 squared, which is 36 pi square centimeters. Also, if you want the answer in decimal, it's 113.09733552923255658465516179806 square centimeters.
A= πr²The diameter is 6, to the radius is 3A= (3.14159) X (3)²A = 3.14159 X 9A= 28.27 cm²
A circle with a diameter of 18 centimeters has an area of 254.47 square centimeters.
The area of a circle with a diameter of 8 centimeters is: 50.27 square centimeters.
