Practice 1
 Write a program to calculate the volume and surface
area of a sphere from its radius, given as input. Here are
some formulas that might be useful:
V = 4/3𝜋𝑟
A = 4𝜋𝑟

Practice 2
 Two points in a plane are specified using the
coordinates (x1,y1) and (x2,y2). Write a program that
accepts two points and determines the distance
between them.
 Distance =
(𝑥2 − 𝑥1)2 +(𝑦2 − 𝑦1)2

Practice 3
 Write a program that distinguish whether the input
numbers are integer or not. The program should first
prompt the user for how many numbers are to be
entered. It should then input each of the numbers and
print whether it is an integer number or not.
* Integer does not mean the type of variable in this problem.
For example, the program should consider 3.0 as an integer number.

Practice 4
 A Fibonacci sequence is a sequence of numbers where
each successive number is the sum of the previous two.
The classic Fibonacci sequence begins: 1, 1, 2, 3, 5, 8,
13, … Write a program that computes the nth Fibonacci
number where n is a value input by the user. For
example, if n = 6, then the result is 8.
