How do you find the circumference of a circle if the diamter is 40cm?
circumference = pi*40cm
How do you find the raduis of a circle knowinng only the circumference?
Radius = circumference/pi
What is the formula to find the circumference of a circle with the raduis given?
Circumference of a circle: 2 x pi x radius.
To the nearest hundredth what is the radius of a circle with a circumference of 7?
to find the raduis of any circle, divde the diameter by 2. in this case, the answer would be 3.50
How do you found the raduis of a circle?
Well, if you know the diameter of the circle already, then you can divide it by half to get the radius. If you don't have the diameter however, then you simply have to find the middle of the circle and measure from the middle of the circle to the edge. That would be your radius.
How do you find the raduis of a circle if you know the density?
You cannot.A circle has no mass nor volume and so the concept of density is not appropriate.Also, the word is radius, not raduis!
How do you find the circumference of a circle if the diamter is 40cm?
circumference = pi*40cm
How do you find the raduis of a circle knowinng only the circumference?
Radius = circumference/pi
What is the formula to find the circumference of a circle with the raduis given?
Circumference of a circle: 2 x pi x radius.
Find the area of a circle whose radius is 2 inches?
To find the radius the formula is pi*radius*raduis So it is going to be 2 to the second power.......Leaving you with an answer of 4 inches......Be sure to include pi
How do you find the circumference of a circle when the raduis is a fraction?
The circumference is 2*pi*radius (not raduis) and this formula is applicable whether the radius is an integer, a fraction, or even an irrational number.
To the nearest hundredth what is the radius of a circle with a circumference of 7?
to find the raduis of any circle, divde the diameter by 2. in this case, the answer would be 3.50
Find the raduis in cm of a circle which has a diameter of 68mm?
radius is just 1/2 diameter so the answer is 34mm
How do you find the circumference of a circle if you the raduis?
Circumference = 2*pi*r where pi = 3.14159 (approx) and r is the radius.
How do you found the raduis of a circle?
Well, if you know the diameter of the circle already, then you can divide it by half to get the radius. If you don't have the diameter however, then you simply have to find the middle of the circle and measure from the middle of the circle to the edge. That would be your radius.
How do you find the perimeter of a half circle with the raduis of 7 inches?
The perimeter of a circle is called the circumferenceTo find the circumference of a circle you do 2 times pi times radiusC = 2 * 3.14159 * 7 = 43.98inchesSince this is a half circle you have to take half of the circumference...you answer is 21.99inches
How do you find the raduis if you know the circumference?
Radius (not raduis) =circumference/(2*pi)
