area of circle
The radius of a circle is 8ft. I have 60ft of tile. Is this enough to cover circle. Do you mean you have 60 SQUARE feet of tile? The circle's area is much more than that. How would you find he angle to a circle if half of it is 12 in. ??? and how owuld you find the area of a ...

find the area of the region bounded by y=4x, y=x^3, x=0 and x=2 Check this on paper, but in my mind I see the differential area (x^3-3x)dx integrate that from 0 to 2 y=4x and y=x^3 intersect when x=-2,0 and 2 the vertical boundaries are x=0 and x=2, so the area is the integral...

math
To find the area, but the easiest approach is using Brahmagupta s formula1: If a quadrilateral of side lengths a, b, c, d can be inscribed in a circle, then its area is given by A = sqrt<(s − a)(s − b)(s − c)(s − d)>, where s = (a + b + c + d)/2 ...
