What is the formula for finding circumference and area of a circle?
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
How do you find area of a circle when you have the circumference circle?
Divide the circumference by pi, and that will give you the diameter. Then take half of the diameter (the radius), and plug it into the formula for the area of a circle (A=πr²)
What is the area and circumference of a diameter of 9.3?
The formula for circumference is c = pi*diameter and the formula for area is a = pi*r^2 Therefore, the circumference is 9.3*pi and the area is pi*(4.65)^2 *4.65 since the radius is half the diameter* *You could substitute pi with 3.14, though leaving your answers in terms of pi is better*
What is the area and circumference of a circle with a diameter of 8.5MM?
Circumference: multiply the diameter by pi (approximately 3.1416). Area: Divide the diameter by 2 to get the radius. Then use the formula area = pi x r2, where r is the radius.
What is the formula of a circumference?
circumference=r2pi
What are the similarities of Circumference Formula and Area Formula?
They both are a formula
What are the difference of circumference formula and area formula?
Circumference is the distance around the object and Area is the amount of space it takes up.
What is the Formula of circumference and area of a circle?
The formula for the circumference of a circle is: radius (x) 3.14 (pi) Area is... Radius2 x 3.14
What is the formula for the circumference of a circle from the area?
In order to convert the area of a circle to the circumference of the circle, divide by the radius and multiply by two. The formula for the circumference of a circle is pi times the diameter.
What is the formula for area and circumference of a circle?
The formula for the area of a circle is pi * radius squared. The circumference of a circle's formula is pi * diameter. NOTE: pi equals approx. 3.14
What is the formula for finding circumference and area of a circle?
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
If the area of a circle is 201.06 then the circumference of the circle is?
The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = πr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2πr to find the circumference.
What is the circumference of a circle is 22 units what is the area?
Divide the circumference by (2 x pi) to get the radius. Then use the formula for the area of the circle.
Why is it pie r squared is the exactly formula for circumference?
It isn't. That is the formula for the AREA of a circle!
What is the area and circumference of a 12 yd diameter circle with a formula?
Area = pi*62 Circumference = pi*12 or 2*pi*6
What is the formula to be used if the diameter is given?
The answer depends on the formula for what: the radius, circumference, length of an arc, area, area of sector, area of segment: each one has a different formula.
How do you find the circumference if you a have the area?
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.
