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 a circle if you know the perimeter?
you can divide the perimeter(circumference) by pi(3.14) and then once you get your answer you divide that by two giving you the length of the radius of the circle. ex: perimeter = 34pi 34pi/pi 34/2=diameter 16=radius
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.

An isosceles right triangle is inscribed in a circle Find the radius of the circle if one leg of the triangle is 8 cm?
First you half all the sides, so 4cm, them you multiply by pi, giving the radius as 12pi, or 12.56637061
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 out the radius of a circle?
The radius of a circle is half its diameter (the measure of the circle from one side across to the other).
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
