What does pi radius 2 mean?
That would depend if you mean 2 times the radius times pi (2*pi*r) or the more likely scenario pi times radius squared (pi*r2). 2*pi*r is the formula of the circumference of a 2d circle. Pi*r2 is the formula of the area of a 2d circle.
How do you find the height of a cylinder?
The formula for the volume of a cylinder, which is h(pi)r2, is the area of the base (pi)r2 multiplied by the height (h). If you are given the diameter instead, remember that the diameter is twice the radius.So if we know that V = h(pi)r2, we can rearrange the formula in order to find the height.Divide the whole equation by (pi)r2. The result is: V ÷ (pi)r2 = h OR h = V ÷ (pi)r2.The formula h = V ÷ (pi)r2 means the height (h) is equal to the volume (V) divided by the area of the base (pi)r2.
How much area is 90 feet Radius?
If you mean a circle, use the formula for the area of a circle: A = pi x r2.
Volume of water in a cylinder?
The formula for volume of a cylinder is (pi *r2 )h
What is the formula for the area of a circle with a diameter of 100?
Area = Pi*r2 = Pi*502 = approximately 7,853.98 units2
What does pi radius 2 mean?
That would depend if you mean 2 times the radius times pi (2*pi*r) or the more likely scenario pi times radius squared (pi*r2). 2*pi*r is the formula of the circumference of a 2d circle. Pi*r2 is the formula of the area of a 2d circle.

What is formula for pi r squared?
The area of a circle = pi*r2
What is the formula for finding the surface area of the circle?
A circle doesn't have a surface area because it is a 2D object. The area of a circle is = pi r2. if you mean the surface area of a sphere it is = 4 pi r2
The area of acicle is 28 square meters What is its circumference?
the formula for the area of a circle is (pi)r2 (pi)r2=28m 28/pi = 28/pi r2 = 28/pi r= (28/pi)1/2 the formula for circumference is c=2(pi)r c = 2(pi)(28/pi)1/2 c = 18.7578884...m
What is the formula for calculating surface area of a hemisphere?
The surface area of a whole sphere, of radius r, is 4*pi*r2.The area of the curved surface of a hemisphere is, therefore, 2*pi*r2.The area of the flat surface is that of a circle of radius r, that is = pi*r2.So the total surface area of a hemisphere is 2*pi*r2 + pi*r2 = 3*pi*r2.
What can you calculate with the formula pi x r2 x g?
If g represents height or length then: pi*r2*g = volume of a cylinder
What is the formula for the lateral area of a sphere?
A = 4*pi*r2
What is the formula doe for the area of a circle?
The formula to find the area of a circle is: A = pi * r2
What is the diameter of a circle with 64 as a diametr?
The answer is 3215.36. The formula for pi is A= pi times radius squared or A=pi r2
What is the formula for finding the area of a cirlce?
pi times radius squared: a=pi x r2
How much area is 90 feet Radius?
If you mean a circle, use the formula for the area of a circle: A = pi x r2.
