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
How do you draw the radius of a circle?
A line of any length may act as the radius of a circle. The radius is the distance from the centre to the perimeter of a circle.
How is the diameter related to the radius of a circle?
The radius of a circle is a line that starts at the center of the circle and ends somewhere along the perimeter of the circle. The diameter is a line that starts at the perimeter of a circle, goes through the center of the circle, and ends at the opposite perimeter of the circle. This a diameter is twice as long as a radius and can be thought or as consisting of two radii.
Is radius the peimeter of a circle?
No because the perimeter of a circle is its circumference
What is the equation of the perimeter of a circle?
perimeter = pi * diameter, or 2 * pi * 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.
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
How do you draw the radius of a circle?
A line of any length may act as the radius of a circle. The radius is the distance from the centre to the perimeter of a circle.
How is the diameter related to the radius of a circle?
The radius of a circle is a line that starts at the center of the circle and ends somewhere along the perimeter of the circle. The diameter is a line that starts at the perimeter of a circle, goes through the center of the circle, and ends at the opposite perimeter of the circle. This a diameter is twice as long as a radius and can be thought or as consisting of two radii.
How do you calculate the perimeter of a circle?
The perimeter or circumference of a circle = 2*pi*radius or pi*diameter
What is the perimeter of 21 of a circle?
The perimeter which is the circumference of a circle is: pi*diameter or 2*pi*radius
Is radius the peimeter of a circle?
No because the perimeter of a circle is its circumference
What is the radius of the circle equal to?
Radius of a circle= Perimeter of the circle/2*pi Radius is half the diameter Radius is the length of a straight line from the center point of the circle to the edge of the circle.
What is the equation of the perimeter of a circle?
perimeter = pi * diameter, or 2 * pi * radius
What is the radius of a circle of perimeter 40 cm?
Radius = 40/2pi cm
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
