What is the diameter of a circle if the radius is 4?
Eight.
What is the radius of a circle with a diameter of eight inches?
4 inches The radius of a circle is always half of its diameter (so 8in/2 = 4 in).
What would be the radius of a circle with a diameter of 8 inches?
Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
What is the radius of the circle with the diameter of eight inches?
4 inches
What does diameter of a circle equal if the radius is eight inches?
16 inches
What is the area of a circle whose diameter is twenty-eight meters?
615.752 m2
What is the area of a circle with a diameter of twenty eight?
Area of a circle = πr²A = 3.14159 x 14²A = 615.75
If the area of a circle is about twenty-eight square inches what is the diameter?
If the area of a circle is about 28 square inches the diameter is: about six inches (5.971).
What is the circumference of a circle with a diameter of eight feet?
The circumference is pi times twice the radius, and the diameter is twice the radius, so the circumference is pi times the diameter: 25.13278 feet.
What is the area of a circle that has a diameter of eight inches?
The area of a circle is the number pi (3.14159...) times the square of the radius. The radius is half the diameter. So if the diameter is 8 inches, the radius is 4 inches. Squaring that gives us 4 x 4, or 16 square inches. Multiplying 16 by pi equals an area slightly larger than 50.26 square inches.
What is the radius of eight and one half mm?
the radius is half of a diameter
If circle circumference is 8 what is diameter?
If you divide eight by pi, you get 2.54647909 as the diameter. If you divide eight by 3.14 (simplified pi), you get 2.54777070 as the diameter.
