How can you find the circumference of a circle with radius or diameter?
The circumference of a circle is equal to its diameter times pi. This is also equal to two times its radius times pi.
What does the diameter of a circle equal?
2R or two times the radius.
Is the circumference of a circle is two times the radius?
The circumference of a circle is 2*pi*radius or pi*diameter
How do you find the circumfrence of a circle with the radius?
two times the radius times pi
What is the area of a circle if its diameter is 9 centimeters?
The formula for a circle's area is pi*radius*radius.The diameter is equal to two times the radius.D = 2*radiusSo, the radius is 4.5 cmArea = pi*radius*radius = 3.14159 * 4.5cm * 4.5cm = 63.617 cm2

What does the diameter of a circle equal?
2R or two times the radius.
What is the diameter of a circle if the radius is 5 in?
the diameter is equal to the radius (*) times two. so, the answer is 10 in.
What is diameter and radius?
the radius is a line from the middle of a circle to a point of the circle. the diameter is two times the radius.
Formula of circle?
The formula for the area of a circle is pi times the radius squared. The formula for the circumference of a circle is two times pi times the radius.
Is the circumference of a circle is two times the radius?
The circumference of a circle is 2*pi*radius or pi*diameter
The circumperence of a radius 8.42 If you calculate something with something it makes something?
The circumference of a circle is calculated as the radius times two times pi (3.142). So a circle that has a radius of 8.42 has a circumference of 8.42 X 2 X 3.142. And that is equal to a circumference of 52.91.
How do you find the circumfrence of a circle with the radius?
two times the radius times pi

What is the distance that is twice or two times the radius?
The diameter of a circle is twice its radius
What are diameters in a circle?
The diameter of a circle is the distance from one side of the circle to the other side by a straight line going through the center point of the circle. The longest distance between any two points on a circle. One-half of the diameter is the radius. That is the distance from the center of the circle to any point on the circle by a straight line. The square of the radius (the radius times the radius) times the value of pi is equal to the distance around the circle called the circumference.
How do i calculate area of a circle?
Two times the radius times pi.
