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
What is the circumference of a circle with the radius of 4?
The circumference of a circle with a radius of four is: 25.13
What is the circumference of a circle if the radius is 4m?
A circle with a radius of 4m has a circumference of 25.133m.
What is the circumference of a circle that has the radius of 3.2cm?
The circumference of a circle that has a radius of 3.2cm is: 20.1cm
How do you find the area of a circle when the radius is unknown?
By using the other information supplied about the circle to calculate either its radius (from which its area can be calculated) or its area (if the circle is similar to another with a given area and some ratio between the two circle is given):If the diameter is given: radius = diameter ÷ 2If the circumference is given: radius = circumference ÷ 2πIf the circle is similar to another circle which has a given area, and the length ratio is given; square the length ratio to get the area ratio and apply to the given area.
If the circumference of a circle is 2053 feet what is the radius of the circle?
Given the circumference of a circle the radius is: r = C / 2xPI So the radius of your circle is 326.7451 ft
Given a circle with a radius of 4 which is the circumference?
The circumference is 25.1
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
How do you find length and width given the circumference?
If you mean the diameter and radius of a circle given the circumference it is:- diameter = circumference/pi radius = circumference/(2*pi)
What is the radius of a circle if given the circumfrence?
The circumference (c) of a circle = 2πr (where r = radius). Therefore if you know the circumference, the radius (r) = c/2π.
How do you find circumference of a circle given?
circumference of a circle = 2*pi*radius or pi*diameter
How do you find distance if radius is given?
Diameter of a circle = 2*radius Circumference of a circle = 2*radius*pi
What is the circumference of a 3 inch circle?
circumference= pi(3.14) by the diameter. if your given the radius, double the radius and times by pi.
How do you calculate the circumference of a circle given the diameter or the radius?
Circumference = diameter*pi
What is the circumference of a circle if the radius is 4.83cm?
The circumference of a circle is given by the equation C=2*pi*r (r being the circle's radius). So, the circumference you're looking for is 30.35 cm.
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 find the area of a circle without knowing the radius?
If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.
