How do you find the radius of a circle if you know the circumfrence?
radius = circumference/(2*pi)
What is the radius of a circumference of 64cm?
The radius of a circumference is half of the diameter. To find the radius of a circumference with a length of 64cm, you need to divide the circumference by 2π (since the formula for the circumference of a circle is C = 2πr). So, the radius would be 64cm / (2π) ≈ 10.19 cm.
How do you find the area of a circle to the nearest hundredth?
If you have the radius, then area = pi*r2 which you then round to the nearest hundredth. If you do not know the radius but do know the diameter or circumference, you can calculate the radius. Otherwise you need to measure it.
How do you find the circumfernece of a circle?
If you want an approximate answer, you can measure it with string. If you want an exact answer and know the radius, multiply by 2*pi to find the circumference.
What is The circumference when the radius is 25 in?
THE FORMULA FOR FINDING THE CIRCUMFERENCE IS:CIRCUMFERENCE EQUALS DIAMETER TIMES 3.14In basic words:What do you know?You know you need to find the circumference of the circle, which is the distance all the way around the circle.You know the radius is 25 inches, the radius is the measurement from the center to the circumference of the circle.You know the formula needs the diameter, a diameter being the length of a line connecting two points on the circumference, touching the center of the circle, maintaining a straight line.With all this information, you can figure out that the radius is half the diameter.Now, begin your math.Problem: What is the circumference of a circle when you know the radius is 25 inches?Formula: Circumference= Diameter X 3.14 which is known as pi.Radius Diameter CircumferenceR=25 D=R times 2Replace variable R with the correct number:2525 multiplied by 2 is 50 which means that D=5050 multiplied by 3.14 is 157The circumference is 157
When you know the circumference of a circle how do you find the diameter?
If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
How do you find the radius of a circle if you know the circumfrence?
radius = circumference/(2*pi)
How do you find the radius of a circle if you know the circumferance?
radius = circumference/2*pi
How do you find the circumference if you know radius?
Circumference of a circle = 2*pi*radius
The radius of the circle is 5inches what is the circumference?
The circumference of a circle that has a radius of 5 inches is 10 X pi or approximatly 31.415926535897932384626433832795. If you know the radius you can find the circumference by multiplying it by 2(pi)
How do you find the area of a circle if you only know its circumference?
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
How do you find the circumference of a circle when you know the area?
To find the circumference of a circle when you know the area, you first need to find the radius of the circle using the formula for the area (area = πr^2). Once you have the radius, you can calculate the circumference using the formula for the circumference (circumference = 2πr).
How do you find the radius of a circle if you dont know the circumference?
Well, if you know the diameter you divide that by two to get the radius.
How dou find diameter?
You measure it. If you know the radius (of a circle), you multiply it by 2 to get the diameter. If you know the circumference of a circle, you divide by pi to get the diameter.You measure it. If you know the radius (of a circle), you multiply it by 2 to get the diameter. If you know the circumference of a circle, you divide by pi to get the diameter.You measure it. If you know the radius (of a circle), you multiply it by 2 to get the diameter. If you know the circumference of a circle, you divide by pi to get the diameter.You measure it. If you know the radius (of a circle), you multiply it by 2 to get the diameter. If you know the circumference of a circle, you divide by pi to get the diameter.
How do you find the length of of the radius of a circle?
You can either measure it, or calculate it if you know the diameter (radius = diameter / 2), or the circumference (radius = circumference / (2pi)).
How do you find the radius of the base in a cylinder?
It depends on the values you have. The base of a cylinder is a circle. If you know the circle's diameter, half it to find the radius. If you know the circle's circumference, divide by 2pi to find the radius. If you know the circle's area, divide by pi and take the square root to find the radius.
If a circumference of a circle is 28.26 inches what is the radius of the circle?
Well, isn't that a happy little question! To find the radius of a circle when you know the circumference, you can use the formula: circumference = 2πr. So, if the circumference is 28.26 inches, you can plug that in and solve for the radius. Just divide the circumference by 2π (which is about 6.28) to find the radius. Happy calculating!
