It is 25cm
Subtract 50cm from external diameter.
The volume of a sphere with a diameter of 25cm is about 8181.2cm3
The diameter is 25/pi cm = 7.96 cm
Radius = Diameter/2 Diameter = 2* Radius
Circumference of a disc: 2*pi*radius or pi*diameter
to find the circumfrence you do pi times diameter ( 50* approx 3.14) which gives you 157cm
It is 25cm
Since the diameter is 10cm, the radius is 5cm. The area of the base is 25*pi square cm. We must multiply that base value by the height, which makes 625pi cubic cm.
Subtract 50cm from external diameter.
The volume of a sphere with a diameter of 25cm is about 8181.2cm3
The diameter is 25/pi cm = 7.96 cm
Radius = Diameter/2 Diameter = 2* Radius
to get the diameter from the radius you simply multiply the radius by 2 since the radius is half the diameter. d=2r where d = diameter and r = radius
Radius or diameter in inches or cm. thickness in thousandths or hundredths of an inchor mm.
A radius is one half of a diameter so divide by two to get from a diameter to a radius. Or you can multiply the radius by 2 to get to the diameter.
The length of a radius is not the length of a diameter. The diameter is two times the length of the radius.
