In the circumference formula for a circle what does 2 get multiplied by?
Circumference of a circle = 2*pi*radius
What is the radius of a circle with a circumference of 3.12?
The circumference of a circle is equal to the radius, multiplied by 2 x pi. Thus, in this case, you can divide the circumference by 2 x pi, to get the radius.
Why is pi used to find the circumference of a a circle?
Because the circumference is equal to the diameter multiplied by pi or the radius multiplied by 2*pi.
What is the circumference of a circle that has a radius of 3.9?
24.492, unless you want more digits of pi besides the standard 3.14. The circumference of a circle is equal to the diameter multiplied by pi, or the radius multiplied by two, then multiplied by pi. c = d*pi c = 2*r*pi c = circumference d = diameter r = radius pi = 3.141593
What is the circumference of 2 inch radius circle?
PI or 3.14 multiplied by Diameter or Radius x 2 12.56 approximately
In the circumference formula for a circle what does 2 get multiplied by?
Circumference of a circle = 2*pi*radius
What is the radius of a circle with a circumference of 3.12?
The circumference of a circle is equal to the radius, multiplied by 2 x pi. Thus, in this case, you can divide the circumference by 2 x pi, to get the radius.
How do you find a surcumference of a circle?
Formula for finding the circumference of a circle: 2 multiplied by pi multiplied by radius
What is the relationship for a radius and a circumference?
For any given circle, the circumference is equal to the radius multiplied by 2 x pi.
How do you the radius of a circle if the circumference is 5 inches?
The circumference of a circle is the Diameter multiplied by Pi, or in mathematical notation: * C=πD (Circumference = the quantity of Pi multiplied by the Diameter) OR * C=2πr (Circumference = the quantity of 2 multiplied by Pi multiplied by the Radius) The radius of a circle with a circumference of 5 inches can be found as follows: C=2πr 5 inches=2πr 5 inches/(2π)=r ~0.7958 inches=r
What is the circumference of a circle if the radius is 5meters?
To find the circumference of a circle the equation would be pi multiplied by diameter, or radius squared. the answer would be 31.415 units squared.
What is the equation for determining radius of a circle if you have the circumference?
Circumference = Diameter multiplied by Pi Diameter = Circumference divided by pi Radius = Diameter divided by 2.
Why is pi used to find the circumference of a a circle?
Because the circumference is equal to the diameter multiplied by pi or the radius multiplied by 2*pi.
How is pi in relation to a circle?
Pi is related to the area and the circumference of the circle. The area is Pi multiplied by the radius of the circle squared and the circumference is Pi times the diameter of the circle. if you're wondering how it works, pi is the area of a circle with radius of 1 (unit), and the circumference of a circle with a radius of ½ (unit).
What is the circumference of a circle that has a radius of 3.9?
24.492, unless you want more digits of pi besides the standard 3.14. The circumference of a circle is equal to the diameter multiplied by pi, or the radius multiplied by two, then multiplied by pi. c = d*pi c = 2*r*pi c = circumference d = diameter r = radius pi = 3.141593
How do you find the circomfrence of a circle?
The equation for the circumference of a circle is 2 multiplied by 3.14 (pi) multiplied by the radius. Since the radius is half of the diameter, it can also be calculated by multiplying the diameter by 3.14.
Part of the circumference of a circle?
An arc is part of a circumference of a circle. The circumference itself is an arc length. The circumference of a circle is found by using the formula circumference (C) is equal to 2 multiplied by pi and the radius, or 2 x pi x r, where r is the radius and pi is 3.14.
