What is the formula to find the perimiter?
It depends what shape you are trying to find. If it is a circle, use the following:C = DpiCircumference = Diameter x PiTake the diameter of the circle, or twice the radius, and multiply it by pi, which is ~3.14If it is any other shape, just add up the sides if they are given.
What formula do you use if you know the diameter of a circle and want to find the circumference?
circumference of a circle = pi * diameter.
How do you find the area of a circle with a radius is 3cm?
Use this formula: A = PI(r)2
What formula will you use to find the circumference of a circle whose diameter is 2.2h?
Circumference of a circle = pi*diameter or 2*pi*radius
How do you find the bottom half of a circle?
To find the area of half a circle, use the formula for a circle pi*r^2 divided by 2. pi = 3.14, r = radius (half the distance across the circle)

How do you find the area of a circle from the radius?
Use this formula: A = PI(r)^2
How do you find the area of a segment of a circle?
In order to find the area of a sector of a circle you can use the formula below: pi*r^2 * # of degrees/ 360
How do you find the area of a circle with a radius is 3cm?
Use this formula: A = PI(r)2
When would a architect use the pythagorean theorem?
simply to find area,distance, and perimiter
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 work out perimeter of circle?
To find the circumference (distance around) of a circle, use the formula pi x d (d=diameter)
What formula will you use to find the circumference of a circle whose diameter is 2.2h?
Circumference of a circle = pi*diameter or 2*pi*radius
How do you find the bottom half of a circle?
To find the area of half a circle, use the formula for a circle pi*r^2 divided by 2. pi = 3.14, r = radius (half the distance across the circle)
What is circumference of a circle with 154 square inches?
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.
How do you find out the base of a cone?
It is a circle, so use the formula "pie r squared" to figure it out
