An oval,or more technically an ellipse, has a long ( major) axis and short (minor axis).
If major axis length is a and minor length is b, then area, A is
A = pi x a x b /4 where pi = 3.14 (approx)

There is no volume formula for an oval(4/3)*(pi)*(r1)*(r2)*(r3) is the formula for an oval
how to calculate area of a wire
Half of the height times half of the width time pi (3.1415926535897)
Area in square units = base*height
The formula to calculate the surface area of a 90-degree elbow is A = πDL, where A is the surface area, D is the diameter of the elbow, and L is the centerline radius. The surface area of the elbow is essentially the curved surface area of the elbow pipe fitting. This formula is derived from the mathematical principles of geometry and calculus, specifically the surface area of a cylinder.
