2cm; the diameter of a circle is twice its radius.

2 x pie = 6.2
The lateral area of a cylinder with a diameter of 10cm and height of 2cm is approximately 62.83cm2
The volume is 4.19 cm3
The radius is double the diameter so 4cm.
2cm; the diameter of a circle is twice its radius.
1
Diameter of circle = 2 * Radius of the circle.
Length of a radius is always half the diameter of a circle. This means that the circle has a radius of 2cm.
2 x pie = 6.2
Area= pi*r2If the diameter of the circle is 2cm, the A= pi cm2If the radius of the circle is 2cm, then: A=3.14159*4=12.567 cm2
you half the diamater to get the radius, then you square the radius. Then you times it by 3.14. Always. example. Diameter=4cm then radius =2cm squared=4cm 4x3.14=12.56
A cylinder with a radius of 4cm and a height of 2cm has a volume of 100.53cm3
The lateral area of a cylinder with a diameter of 10cm and height of 2cm is approximately 62.83cm2
The volume is 4.19 cm3
