6. Math Math Pascal Code Example + Ans:= first+second; -
Ans:= second – first; x *
Ans := first * second; ÷ /
Ans := first / second ()
Ans := (first + 2)/second; π PI
Ans := PI; 52
sqr
Ans := sqr(first); √
Sqrt()
Ans:= sqrt(first);

7. You turn: What is the result of the following?
Expression
Answer
Type
2+ 12
5*(8-15)
5 + 6*3
6 + 4/2 – 8
(6+4)/2 – 8
(6+4)/(2-8)
Sqrt(9)
Sqrt(4*4 + 9)
Sqrt(sqr(3) + sqr(4))

8. Translate to Pascal Math Pascal 2(a+c) Ans:=2*(a+c); 3x + 5y
½(b1 + b2)(h)
|z-x|

12. Sample program Input: The radius and height of a cylinder. Process:
Surface area = 2πr2+2 πrh
Volume = πr2h
Output: The Volume and surface area of the cylinder.

13. Hands on Test: Radius of 1 inch and height of 1 inch
Surface area = πr2 + πr2 +2 πrh
Volume = πr2h
Test:
Radius of 1 inch and height of 1 inch
Radius of 2 inches and height of 10 inches
