Answer:
The area of the triangle is calculated as thus:
To calculate the perimeter of the triangle, the measurement of the slant height has to be derived;
Let s represent the slant height;
Dividing the triangle into 2 gives a right angled triangle;
The slant height, s is calculated using Pythagoras theorem as thus
The perimeter of the triangle is then calculated as thus;
For the volume of the cone,
when the triangle is spin, the base of the triangle forms the diameter of the cone;
Where
So,
So,
Base on the above illustrations, the program is as follows;
#include<iostream>
#include<cmath>
using namespace std;
void CalcArea(double b, double h)
{
//Calculate Area
double Area = 0.5 * b * h;
//Print Area
cout<<"Area = "<<Area<<endl;
}
void CalcPerimeter(double b, double h)
{
//Calculate Perimeter
double Perimeter = 2 * sqrt(pow(h,2)+pow((0.5 * b),2)) + b;
//Print Perimeter
cout<<"Perimeter = "<<Perimeter<<endl;
}
void CalcVolume(double b, double h)
{
//Calculate Volume
double Volume = (1.0/3.0) * (22.0/7.0) * pow((0.5 * b),2) * h;
//Print Volume
cout<<"Volume = "<<Volume<<endl;
}
int main()
{
double b, h;
//Prompt User for input
cout<<"Base: ";
cin>>b;
cout<<"Height: ";
cin>>h;
//Call CalcVolume function
CalcVolume(b,h);
//Call CalcArea function
CalcArea(b,h);
//Call CalcPerimeter function
CalcPerimeter(b,h);
return 0;
}

Explanation:
The computation of the velocity by using the following formula is
As we know that
where,
Displacement is 10 meters
Total time taken is 30 seconds
Now placing these values to the above formula
So, the velocity of Dash is
We simply applied the above formula so that we can get the velocity and the same is to be considered
