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.
If the radius of a circle is 2cm what is the diameter?
Diameter of circle = 2 * Radius of the circle.
What is the diameter of a circle with a radius of 2 Centimeters?
4cm
What is the circumference of a 4cm circle?
Circumference of a circle = 2*pi*radius or diameter*pi
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 length of a biggest chord of a circle of radius 4cm?
It is the diameter which is twice the radius giving a length of 8 cm
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
If the radius is 2cm what is the diameter?
radius is half the diameter. so 4cm.
What is the circumference of a circle with a radius of 4cm?
The circumference of a circle with a radius of 4cm is: 25.13 cm (r x 2 x pi)
What is the circumference of a circle if the diameter is 4cm?
Circumference = Pi X Diameter = 3.1415 X 4cm = 12.566cm
What is the area of a circle with radius of 4cm?
A circle with a radius of 4 cm has an area of 50.27 square cm.
