Answer 1

You should use floating-point numbers rather than integers.

this: ' float Area = pi * ((b * b) / 4.0) * ((2.0 * a - b) / (2.0 * a + b));' ?

Answer 2

Check your user define function, it is the area of an ellipse, right?

This is the correct user define function will be for the area of an Ellipse:

float Area = pi * a * b / 4 * (2.0 - ((a - b) * (a - b)) / ((a * a) + (b * b)));

Answer 3

No it is to calculate the circel area inscribed in an isosceles triangel

Answer 4

Very attentive and clever! Thank you!
