If the diameter of an circle is 20mm what is the area?
For a circle with a diameter of 20 mm, it's radius, which is half that, will be 10 mm. The area (A) of a circle is pi (about 3.1416) times the radius (r) squared (r2). Here's how we work it: Acircle = pi x r2 = 3.1416 x 102 = 3.1416 x 100 = 314.16 mm2
A part of a circle called?
Part of a circle's circumference is an arc
A number that describes a part of a set of a part of a whole that is divided into equal parts?
A fraction.
What is part of a circumference of a circle called?
Part of the circumference of a circle is called an arc.
Faces on a cone?
A cone has two faces. The large triangular part and the circular part at the bottom.
Is acircle a geometric?
A circle is a round geometrical shape
When a shaded circle is inside a square what fraction of the square is shaded?
It ultimately depends on the areas of the two shapes: Acircle = pi*r2 Asquare = l2 Fraction shaded = Acircle / Asquare = pi*r2/ l2 If the circle fills the square (e.g. l=2r) then the formula simplifies considerably: pi*r2/4r2 = pi/4
Formula for finding the area and perimeter of acircle?
Area of a Circle:pi X r2Where "r" is the radius.Perimeter of a Circle:2 X pi X rORpi X dWhere "r" is the radius and "d" is the diameter.
Can outward force that makes objects moving on acircle fly out is antrifugalforce?
Outward force that makes objects move in a circle, then make them fly out of the circle is centrifical force. If you think in terms of a centrifuge, it spins so fast that the force could push the items out if they were not held down.

How and why does a fairy ring form?
Fairy rings are made up of mushroom fungus growing in a ring shape. Mushrooms do not make their own food as plants do but much feed off of nutrients found in the soil. When the nutrients have been exhausted in the mushrooms current position its offspring must spread outwards to find new nutrients. This cause them to grow in an ever expanding ring.
How many gallons are in a sixteen foot by four foot deep pool?
If you mean a round pool that is 16 feet in diameter and 4 feet deep, the bottom area is given by: Acircle = pi x r2 In this expression, r is the radius of the pool, which is half the diameter, or 16 / 2 = 8' Acircle = pi x 82 = pi x 64 = 201.06 square feet A cylinder (which is the shape the water takes confined in the pool) has a volume given by: Vcylinder = pi x r2 x h The only "new" variable there is h which is the height. Let's finish. Vcylinder = pi x r2 x h = 201.06 x h = 201.06 x 4 = 804.25 cubic feet There are about 7.48 gallons in a cubic foot, and if you have cubic feet to convert to gallons, you'll multiply by that 7.48, which will be 804.25 x 7.48 = 6015.8 gallons The methodology was correct, and the numbers do not lie, so yes, there is really that much water in a pool with those dimensions and that water level.
What is the area of a fountain that is 10 ft from the center to the edge of the base?
If you have a circular fountain that is 10 feet from the center to the edge, it has a radius of 10 feet. The formula for the area (A) of a circle is pi (about 3.1416) times the square of the radius (r) of the circle. For a circle with a 10-foot radius, here's the formula: Acircle = pi x r2 = 3.1416 x (10 ft)2 = 3.1416 x 100 ft2 = 314.16 ft2 = 314.16 square feet
How many one-fourth inch diameter spheres in a 360 cubic inch cylinder?
VCylinder = ACircle x h = pi x (r^2) x h = 360VSphere = (4/3)(pi)(r^3) where r = (0.5)(D) = (0.5)(0.25 in) = 0.125 inVSphere = (4/3)(3.1416)(0.125^3) = 0.00818 cubic inchesIf we just do this calculation based on sheer Volume, not taking into account the shape of the sphere and the shape of the cylinder, then the answer is as follows:(360 / 0.00818) =44,003
