Question No$.1$: Functions in Python.

Given Write a Python program that includes the following functions:

Function $1$: Calculate the area of a right triangle. Use the formula Area $a\frac{b}{2},$ where a and $b$ are the triangle base and height.

Function $2$: Calculate the volume of a cone of height $h$ and base radius $r.$ Use the formula Volume $=r^2\frac{h}{3}$

Test your program with the following input parameters:

Triangle with $a=5cm$ and $b=3cm$

Cone with $r=5cm$ and $h=15cm$

Cone with $r=10cm$ and $h=10cm$
