It depends on the type of figure you are looking at. For a: rectangle: Length× height circle: π x radius2 triangle: ½ x base x height
Yes mathematical equations can be solved.
One half its base times its height, or 1/2 b*h.
4 pi r 2
That depends on the shape of the object. For a sphere (globe or ball) the formula for its surface area is 4 x pi x r2 where pi = 3.1416 eg for a sphere of radius 3 cms the surface area = 4 x...
