Using the formula below, write a program incorporating a function tocalculate the volume of a truncated cone given the height, the radius of the base, and theangle in degrees formed by the centerline and the side of the cone at the apex. Theformula for the volume is:

TR3 (R-y tan 0) 3 tanb 3 tanG where y is the height, R is the radius, and is the angle in radians. Use a preprocessor command to define PI. In function main, prompt the user for the values of R and y in meters, and angle in degrees, and read in the values. Then call a function. Coneyolume, to calculate volume of the truncated cone. Print the volume in function main with 3 decimal digits. Function ConeVolume receives radius, height, and angle of cone in degrees and calculates the volume of the truncated cone. It returns the volume to function main Test with the following values: R 2.5 meters y 3 meters angle 30 degrees
