How do you find the circumference if you a have the area?
Andra8970
You can find the circumference of a circle if you know its area by using the formulas for area and circumference. First, use the formula for area: A = pi r2. Replace A with the number for the area. Solve the formula for r, the radius of the circle, dividing A by pi and taking the square root of the answer. Once you have the number for r, the radius of the circle, plug that value in place of r in the formula for the circumference: C = 2 pi r. Then you can calculate the circumference of the circle by multiplying pi times twice the radius.

How do you find the height of a cylinder if you have the circumference and the surface area?
you divide the surface area by the circumference.
How do you find the area of a circle knowing only the circumference?
To find the area of a circle knowing only the circumference, you can use the formula A = (C^2) / (4π), where A is the area and C is the circumference. Square the circumference, then divide it by 4π to get the area.
How do you find the circumference of a circle with the area given?
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
Find the area and circumference of 9.5?
If the object is a circle and if 9.5 is the diameter, the area is 70.88 and the circumference is 29.85
Find the area and circumference of 24?
If the object is a circle and if 24 is the diameter, the area is 452.39 and the circumference is 75.4
How do you find the area of a cirle with the circumference?
Area = circumference squared... You do circumference divided by 4,... and then divide that by Pi.
How do you find the height of a cylinder if you have the circumference and the surface area?
you divide the surface area by the circumference.
Find the circumference of a circle with an area of 82?
The circumference is: 32.1
How do you find the area of a circle knowing only the circumference?
To find the area of a circle knowing only the circumference, you can use the formula A = (C^2) / (4π), where A is the area and C is the circumference. Square the circumference, then divide it by 4π to get the area.
How do you find the circumference of a circle with the area given?
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
Find the area and circumference of 9.5?
If the object is a circle and if 9.5 is the diameter, the area is 70.88 and the circumference is 29.85
Find the area and circumference of 24?
If the object is a circle and if 24 is the diameter, the area is 452.39 and the circumference is 75.4
Find the area of a circle when the circumference is 10in?
The area of a circle when the circumference is 10 inches is: 7.96 square inches.
How do you find circumference and area of a circle if radius is known?
Circumference = 2*pi*radius Area = pi*radius2
How do you find out the area if you have the circumference?
Circumference = 2*π*r where r is the radius So r = circumference/(2*π) Then Area = π*r2
How do you find the radius of a circle using an equation?
What do you have? The area of the circle or the circumference? Area: divide the area by pi, then square root it Circumference: divide the circumference by 2 then divide it by pi
How do you calculate circumference and area of pi?
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
