Radius | area | circle calculator

Write a C++ program that stores the number 105.62 in the variable firstnum, 89.352 in the variable secnum, and 98.67 in the variable thirdnum. Have your program calculate the total of the three numbers and their average. The total should be stored in the variable total and the average in the variable average. Use the cout object to display the total and the average.

 Algorithm

STEP#1    Start

STEP#2    Declare the variable Firstnum, Secnum, Thirdnum, Total,  Average

STEP#3    Assign value 105.62 to Firstnum

STEP#4    Assign value 89.352 to Secnum

STEP#5    Assign value 98.67 to Thirdnum

STEP#6    Calculate Total and Average

STEP#7    Total= (Firstnum+Secnum+Thirdnum)

STEP#8    Average= (Total/3)

STEP#9    Display the Total

STEP#10    Display the Average

STEP#11    End

Code

#include <iostream>

using namespace std;

int main()

{

    float radius,area,circum;

    radius=3.5;

    area=3.14*(radius*radius);

    circum=2*3.14*(radius);

    cout<<area<<"\n";

    cout<<circum<<"\n";

    return 0;
