If the diameter is 4.4 the radius is 2.2 because to get the radius you divide the diameter by 2.
The diameter of a circle is twice the radius. For a circle with a radius of 22 feet, the diameter would be 22 feet × 2, which equals 44 feet. Therefore, the diameter of a 22-foot circle is 44 feet.
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)
Circumference = (pi) x (diameter) = (pi) x (2 x radius) = 44 pi = 138.23 (rounded)
Radius = Diameter/2 Diameter = 2* Radius
Diameter = 2*Radius So, in this case, diameter = 44 cm
The diameter of a circle is twice the radius. For a circle with a radius of 22 feet, the diameter would be 22 feet × 2, which equals 44 feet. Therefore, the diameter of a 22-foot circle is 44 feet.
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)
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)
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
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
