REM Program to find total surface area of hemisphere
CLS
INPUT "Enter the radius: "; r
tsa = 3 * 3.14 * r ^ 2
PRINT "Total Surface Area of a hemisphere is: ";tsa
END
Output
Explanation
Let’s first see the formula: tsa = 3 * pi * r ^ 2, where the value of pi is 3.14. So, we can determine the total surface area of any hemisphere by taking the radius of the hemisphere from the user and multiplying the value of pi by 3 and the radius of the hemisphere raised to the power of 2.
