carpenters, and also architects
haha
Using 3.14 as Pi the area of circle is: 0
circumference = 11*3.14 = 34.54 cm
We use it to calculate the circumference of a circle.
Use the formulae for the area and circumference of a circle, replacing the symbol for the radius or the diameter with the known radius or diameter. As a reminder, the radius is 1/2 the diameter.Circumference = pi x diameter area = pi x radius squared
To calculate the area/circumference of a circle when designing something circular with a limited amount of material. i.e. you have to design a bronze circle and only have 27 sq ft of bronze. You have to calculate the circumference to see if you need to make the circle smaller or not.
Divide the circumference by (2 x pi) to get the radius. Then use the formula for the area of the circle.
The circumference and area of a circle, with radius r is: circumference = 2*pi*r and area = pi*r2 Use the first to calculate r and then the second to calculate the area.
The area of a circle with a circumference of 9.42 inches is: 7.06 square inches.
Suggestion: Divide the circumference by (2 x pi) to get the radius. Then use the standard formula for the area of a circle.
The area of a circle with radius r is pi*r*r and its circumference is 2*pi*r Use the first to find r and then use that value of r in the second to find the circumference.
if it is the radius you can find area or circumference
They both use pi:- circumference = 2*pi*radius or diameter*pi area = pi*radius2
Use the standard formula for the area of a circle to find out the circle's radius. Then multiply that by 2 x pi, to get the circumference.
you use pi to calculate the area or circumference of a circle
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.
If the radius of the circle is 1, the area is pi. (3.14159 square units) The circumference is twice that. (6.28318 units)
Circumference is what you use when finding the area of a circle.
