If the diameter is 4.4 the radius is 2.2 because to get the radius you divide the diameter by 2.
Circumference is equal to pi (3.14) times Diameter. Diameter is twice the radius. So take radius (44) multiply by 2= 88. Multiply 88 times 3.14, and that is the circumference.
Circumference = (pi) x (diameter) = (pi) x (2 x radius) = 44 pi = 138.23 (rounded)
Radius = Diameter/2 Diameter = 2* Radius
Circumference = (pi) x (diameter) = (pi) x (2 x radius) = 44 pi = 138.23 (rounded)
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.
Diameter = 2*Radius So, in this case, diameter = 44 cm
Circumference is equal to pi (3.14) times Diameter. Diameter is twice the radius. So take radius (44) multiply by 2= 88. Multiply 88 times 3.14, and that is the circumference.
Circumference is about: 44 Area is about: 153.94
Circumference = (pi) x (diameter) = (pi) x (2 x radius) = 44 pi = 138.23 (rounded)
Radius = Diameter/2 Diameter = 2* Radius
A circle with a radius of 22 inches has a circumference of 138.23 inches.
Circumference = (pi) x (diameter) = (pi) x (2 x radius) = 44 pi = 138.23 (rounded)
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
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.
radius = diameter/2
The radius is half the diameter. So, if the diameter is 8, then the radius is 4.
