How do you find the circumference of a circle using the radius?
Circumference = 2*pi*radius So the radius = circumference/2*pi
What is the formula for the diameter or a circle?
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
If the circumference of the circle is 75.36 what is the radius?
To find the radius of a circle when given the circumference, you can use the formula: circumference = 2 * π * radius. Given that the circumference is 75.36, you can plug this value into the formula and solve for the radius. First, divide the circumference by 2π to find the radius. The radius of the circle would be 75.36 / (2 * 3.14159) ≈ 12. The radius of the circle is approximately 12 units.
What is the formula of circumference?
The circumference of a circle is two times pi times the radius.
What is the radius of a circle whose circumference is 94.2?
To find the radius of a circle when given the circumference, you can use the formula C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 94.2, you can plug this value into the formula: 94.2 = 2πr. To find the radius, you can rearrange the formula to solve for r: r = 94.2 / (2π) ≈ 15.0 units. Therefore, the radius of the circle is approximately 15.0 units.
