The circum. = pi x diameter so divide circum. / pi = diameter
Area = 12.6 cm2Circumference = 12.6 cm
A sphere with this volume has a diameter of 9.1416 cm, a surface area of 262.54 square cm and a circumference of 28.719 cm.
The approximate diameter of a circle whose circumference is 21cm is: 6.68cm
The area of a circle whose diameter is 12 inches is: 113.1 square inches.
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.
The volume of a sphere whose diameter is 25 centimeters is 8,181 cubic centimeters
A right circular cone whose slant height is 9 inches and whose base has a diameter of 2 inches will have a volume of 36.757 cubic inches.
40.8cm
Diameter is twice the radius, so 15 cm.
The circum. = pi x diameter so divide circum. / pi = diameter
