If the diameter is 5 feet then the radius is 2.5 feet. If the circumference is 5 feet then the radius is 0.79577 feet.
The radius is 1/2 of the diameter. A diameter of 10 has a radius of 5.
The radius of the circle is the length between the middle of the circle and any of the sides. It is also half the lenght of the diameter.
diameter = radius × 2 → radius = diameter ÷ 2 = 10 cm ÷ 2 = 5 cm
5 inches
If the diameter is 5 feet then the radius is 2.5 feet. If the circumference is 5 feet then the radius is 0.79577 feet.
The area of a circle is PI times the radius of the circle squared. The radius of a one foot diameter circle it 1/2 or .5 feet. .5 squared is .25 PI is 3.1416 3.1416 times .25 = .79 square feet So, there are about .8 square feet in a 1 foot diameter circle.
The diameter is twice the radius so a circle with a radius of 2.5 will have a diameter of 5.
The radius is 1/2 of the diameter. A diameter of 10 has a radius of 5.
Diameter of a circle is always twice the radius. So if the radius is 2.5 then diameter is 2x 2.5=5
The radius of the circle is the length between the middle of the circle and any of the sides. It is also half the lenght of the diameter.
10 cm; the diameter of a circle is twice its radius.
The diameter is double the radius of a circle. So you get 5 inches for the diameter.
Radius = diameter/2 = 5 cm
5 because the radius is half of the diameter
A circle's radius is always 1/2 of the circle's diameter, so the radius of a circle of 5-inch diameter is 2-1/2 inches.
10 cm (diameter is double the radius)
