Describe the effect on the area of a circle when the radius is doubled?
the radius is from the center of the circle to the edge so that's how you find the radius.
What is the radius of a circle if the area is 153.86cm2?
The area of a circle is 153.86cm².find the radius of the circle
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.
How do you find the diameter of a circle when you know the radius?
Diameter = 2*Radius
What is the radius of a 90 degree circle?
The radius is a lenght, and it's impossible to find out the radius if you don't give any information about the size of your circle.
How do you find the radius of a circle with the circumference in terms of pi?
find the radius of a circle with circumference of 42.1
How do you find the radius of the base in a cylinder?
It depends on the values you have. The base of a cylinder is a circle. If you know the circle's diameter, half it to find the radius. If you know the circle's circumference, divide by 2pi to find the radius. If you know the circle's area, divide by pi and take the square root to find the radius.
How do you find the director circle of circle?
The director circle of a circle with radius r is a concentric circle with radius r*sqrt(2).
How do you find the radius of a circle if you know the radius?
You already know the radius.
How do you find distance if radius is given?
Diameter of a circle = 2*radius Circumference of a circle = 2*radius*pi
How do you find what a diameter of a circle is?
It is twice the radius of a circle
How do you find the radius of circle with area 144pi?
Equation for the area circle = pi x radius squared If the area is 144pi, then you need to find the square root of 144, which is 12. Therefore, radius = 12
How do you find the area of a circle for 5 th grade?
To find the area of a circle for fifth grade, what one has to do is to first find the radius, the radius is the distance from the central point to all points on the circle, once the radius is found, square the radius. Then multiply the squared radius by pi.
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 circumference of a circle if you have radius?
For a circle, circumference = 2 x pi x radius.
