If the area of a circle is 25 square units what is the radius of the circle?
area equals pi r squared therefor r squared equals area over pi. Now find square root of r squared and you have "R" (radius) = 2.821
Does the area of a circle equal pi?
no, the area of a circle equals pi times the radius squared or circumference times diameter over four.
What fraction of the area of a circle of radius 5 lies between concentric circles of radius 3 and 4?
The area of a circle with radius 5 is 25 pi. Concentric circles with radius 3 and 4 have areas of 9 pi and 16 pi. The concentric circle with radius four consumes the circle with radius 3. 25 pi minus 16 pi leaves 9 pi of the circle with radius 5 left over. 16 pi is slightly over three-fifths of the circle with radius 5.
What is x2 over 64 minus y2 over 121 equals 1?
This is an equation that describes an ellipse. Its center would be located at the point (0, 0), its x radius would be 8, and its y radius would be 11.
What is the radius of 7 over 2?
Seven over teo is a number (3 1/2 or 3.5) and has no radius. Only a circle has a radius.

How many acres in a 500 meter radius?
A circle with a 500 meter radius has an area of a little over 194 acres. However, if you're going to use meters for the radius you should use hectares for the area; it's pretty close to 78.54 hectare.
How do you find the circumfirence of a circle?
The circumference of a circle is the distance all around the edge of the circle. To find the circumference of a circle, you use the formula C equals 2 times pi times r, where pi is equal to 22 over 7 and r is the radius.
What equals force divided by pressure?
Force divided by pressure is equal to the area over which the force is applied. This relationship is defined by the formula: Area = Force / Pressure. It describes how the force distributed over a given area affects the pressure exerted on that area.
How do you find the mean of x over y equals a over b?
Find the derivative of Y and then divide that by the derivative of A

What is the formula for determining pressure?
Pressure equals force over area. P=F/A.
