How to find the volume and surface area of a cylinder

The volume of the cylinder is the density of the cylinder or how much amount of any material can be immersed in it. Volume of cylinder is given by .

Cylinder Volume = πr²h

The surface area of a cylinder is defined as the sum of the curved surface and the area of two circular bases of the cylinder.
The surface area of cylinder = curved surface + area of circular base
 

Where r is the radius of the cylinder and h is the cylinder height

 

How to find volume and surface area of a cylinder in GO Program

--Here we are showing how to find the volume and surface area of a cylinder in the Go language. Here variable Rds, Hgt holds the radius and height of the cylinder. Other variables SA, Vol, LSA, TA are used as the result variable of surface area, volume, lateral surface area, Top or bottom surface area. Use the mathematical functions for the calculation. Volume is found by using  πr²h and surface area by using 2πr² + 2πrh. Finally print the results. Given below are the steps which are used in the Go program. 

ALGORITHM

STEP 1: Import the package fmt, math

STEP 2: Start function main()

STEP 3: Declare the variable Rds, Hgt, SA, Vol, LSA, TA

STEP 4: Read the radius and height of the cylinder Rds, Hgt

STEP 5: Calculate the surface area by using 2πr² + 2πrh

STEP 6: Calculate the volume by using πr²h

STEP 7: Calculate the lateral surface area by using 2πrh

STEP 8: Calculate the top or bottom surface area by using πr²

STEP 9: Print the SA, Vol, LSA, TA using fmt.Println()

 

                                          package main

import (
    "fmt"
    "math"
)

func main() {

    var cyRa, cyHt, cySA, cyVol, cyL, cyT float32

    fmt.Print("Enter the radius  of Cylinder = ")
    fmt.Scanln(&cyRa;)
    fmt.Print("Enter the height Cylinder = ")
    fmt.Scanln(&cyHt;)

    cySA = 2 * math.Pi * cyRad * (cyRa+ cyHt)
    cyVol = math.Pi * cyRa * cyRa * cyHt
    cyL = 2 * math.Pi * cyRa * cyHt
    cyT = math.Pi * cyRa * cyRa

    fmt.Println("\nThe volume of a Cylinder                = ", cyVol)
    fmt.Println("The surface area of a Cylinder            = ", cySA)
    fmt.Println("The lateral surface area of a Cylinder    = ", cyL)
    fmt.Println("Top or bottom surface area of a Cylinder    = ", cyT)

                                      

Enter the radius of Cylinder = 5
Enter the height Cylinder = 9
The volume of a Cylinder                = 706.8583
The surface area of a Cylinder            = 439.823
The lateral surface area of a Cylinder    = 282.7433
Top or bottom surface area of a Cylinder    = 78.5398
