radius=4cm diameter=8cm *radius is half the diameter
If the radius of a circle is 2cm what is the diameter?
Diameter of circle = 2 * Radius of the circle.
If the diameter is 8cm how long is its radius?
Its radius would be 4cm long. You split it in half.
If the radius is 2cm what is the diameter?
radius is half the diameter. so 4cm.
What is the diameter of a circle if the radius is 2cm?
The radius is double the diameter so 4cm.
What is the diameter of a circle if it has a radius of 4cm?
The radius is half the diameter. So multiply the radius by 2.
What is the diameter of a circle with a radius of 2 Centimeters?
4cm
How do you work out the area of a circle given the diameter?
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
What is the lateral area of a cylinder whose diameter is 4 cm and whose height is three times the radius?
The lateral area of a cylinder whose diameter is 4cm and whose height is three times the radius equals approximately 75.4cm2
