Why is the circumference of a circle diameter times pi or 2 radius times pi?
Because 2 times the radius is equal to the diameter of the circle
What is the circumference of the circle with a 6 inches radius?
The circumference of a circle equals the diameter times pi. The diameter is two times the radius. So a circle with a radius of 6 would have a diameter of 12, and a circumference of 12pi.
The radius of a circle is multiplied by 7 Its area is times bigger than the original circle?
The relationship between a circle's radius and it's area is: a = πr2 so if the radius of the circle increases by 7 times, the area will increase by π72 times, or 49π, which is approximately equal to 153.938
How do you figure out the diameter of a circle?
Pi times the radius of the circle squared = area And diameter is simply the radius x 2, since the radius is half the length of the circle.
What is Pi R Squared?
The formula to get the area of a circle ("R" being the radius of the circle). Radius means the distance from the center of the circle to the edge.It means pi times radius squared which is the formula for finding the area of a circle.
How do you take a circle and enlarge it by 150 percent?
Increase the radius sqrt(1.5) = 1.2247 times.
What is formular of circle?
Area of a circle: pi times radius squared Circumference of a circle: 2 times pi times radius or diameter times pi
What is the the length of a circle that has a radius of 30?
The circumference of a circle with radius 30 is equal to 2 times the radius times pi, or about 188.5.
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.
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.
How you get the area of a circle?
A= Area of the circle¶= Pi (About 3.14)r= Radius squared (Radius times radius)3.14 * Radius squared
Why is the circumference of a circle diameter times pi or 2 radius times pi?
Because 2 times the radius is equal to the diameter of the circle
A circle has a radius of 12 in Find the diameter of the circle?
diameter is 2 times the radius 24
How do you find ratio of area to radius?
In a circle, the area of the circle is pi times the radius squared
What is the ratio of the circumference to the radius of the circle?
The ratio of the circumference to the radius of the circle is 2 times pi
How do you find a area a circle?
The answer depends on what information you are given.
What is the area and the circumference of a circle?
area: pi times radius squared circumference: pi times radius
