If it is a circle than the formula to find the area is pi*(r)^2, which gives you 616.
If we're talking about a circle, then Area = pi R2 .
A = (3-1/7) x (14)2 = (22/7) x (196) = 616 square units.
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
no, the area of a circle equals pi times the radius squared or circumference times diameter over four.
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.
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.
Working in degrees, the angle of the greater radius, minus the lesser radius, all over 360, gives the proportion of the area of the circle that is bounded by the radii. This can then be multiplied by the area of the whole circle to give the bounded area.
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

to find the volume of a sphere the equation is v= 4 over 3 x pie x the radius cubed
Using 3.14 as Pi the area of circle is: 28.259999999999998

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.
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.
If the surface area of a sphere is 16 m2, find the radius.4 pi r2 | 4 pi = SA | 4 picross out 4 pi till left with r2r2 = SA |4 pi./r = ./SA|4 pir = ./SA|4 pir = ./16| 4 pi= 1.13m./ means root| means divided or over
Find the derivative of Y and then divide that by the derivative of A
Pressure equals force over area. P=F/A.
Earth's radius is a little less than 4000 miles.
