Question

This is a C++ statement, when it comes to Algebra, this is very difficult for me to solve this, please help me solve this problem with step-by step solutions

Question 27 10 pts (SHORT ANSWER) Write C++ statements to do the following (number your answers): 1. Declare a constant PI and initialize it with 3.1415 2. Declare a variable volume of type double 3. Calculate the volume of the cone and store it in the variable volume . Given the formula to compute the volume of a cone is: Ibrº (%) • Assume: the variables r and h are already defined and initialized with values 4. Display the computed volume on the console as follows (make sure to display the value of the volume with two decimal places): Volume of Cone = XX.XX (where XX.XX is the value stored in the variable volume) BIVA-A-IE21 x 5 5-2 VX 6 TT 12pt Paragraph O words

Answer 1

code:

==============================

#include <iostream>
#include <iomanip>
using namespace std;

//1.declare a constant pi
# define PI 3.1415
int main() {
//2.declare a varaible volume of type double
double volume;
int r=2,h=5;
//3.calculate volume of cone
volume = PI*(r*r)*(h/3);
//4.Display the computed volume
cout<<"Volume : "<<fixed<<setprecision(2)<<volume;
}
