What is the formula for finding the radius of a circle when you have the perimeter?
2*pi*radius = perimeter or circumference of a circle radius = circumference/2*pi
What is the equation of the perimeter of a circle?
perimeter = pi * diameter, or 2 * pi * radius
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
What is the radius of a circle of perimeter 40 cm?
Radius = 40/2pi cm
How do you find the perimeter of a shape that has a semicircle?
To find the perimeter of the curved section of the semi-circle: Perimeter of semicircle = Pi x radius If you also need to the find the perimeter of the straight part of the semicircle (the diameter), it is simply double the radius.
What is the formula for finding the radius of a circle when you have the perimeter?
2*pi*radius = perimeter or circumference of a circle radius = circumference/2*pi
Is the radius the measurement of the perimeter of a circle?
No.
Can you give me a sentence with the word radius?
The radius is found inside of the perimeter.

Formula for perimeter of a circle?
Circumference or perimeter = 2*pi*radius or pi*diameter
What is hydraulic mean radius?
Hydraulic Mean Radius = Cross sectional area of conduit divided by the inside (wetted) perimeter.
What is difference between a radius and a diameter?
Radius is the shortest distance via straight line between the center point of the circle and its perimeter. Diameter is the greatest distance via straight line from one perimeter of the circle to the opposite perimeter. Diameter = 2x Radius.
What is the perimeter of a circle with a radius of 5cm?
The circumference of a circle with a radius of 5cm is: 31.42 cm
