What is Pi R Squared?
The formula to get the area of a circle ("R" being the radius of the circle). Radius means the distance from the center of the circle to the edge.It means pi times radius squared which is the formula for finding the area of a circle.
What is the formula for finding the centroid of a circle?
2[4(radius)/3(pi)]
What is the area of a circle if the radius of a circle is 3.7cm?
The formula for finding the area of a circle is : pi(r) squared. So, that answer would be 13.69cm multiplied by pi, which is nearest to 3.14.
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 find a diameter of a circle?
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)
Why do you use the radius in the formula of finding the area of a circle?
Area of circle = pi*(radius)2
What is the formula for finding perimeter of a circle?
The formula for the circumference of a circle is pi * diameter or (2 radius.)
What is the formula for finding the radius of a circle when you have the perimeter?
2*pi*radius = perimeter or circumference of a circle radius = circumference/2*pi
What is Pi R Squared?

What is the formula for finding an area of a circle?
The area of a circle with a known radius can calculated using the following formula where r is the radius : A = Pi(r)2

Hell are you talking about?!? A radius is a dimension of a circle! A rectangle has no stinking radius!
What is formula ofr finding area of a circle?
Area of a circle = pi*radius squared
Formula for finding the area if you have radius?
Area of a circle = pi*radius2
How do you Find The Perimeter of a Circle With Radius?
this is called finding the circumference. The formula is 2*pie*radius
What is the formula of finding the area of a circle?
Pi * R squared, where R is the radius of the circle in question
What formula is pi d?
It is the formula for finding the circumference of a circle which is the same as 2*pi*radius
What is the formula for finding the centroid of a circle?
2[4(radius)/3(pi)]
