## Import

Libraries contain additional functions to use in your programs. Before you can use a library, you must import it with the `import` keyword. Example of importing the `math` library and using its `sqrt()` function to calculate the square root of a number:
```import math

number = 36
square_root = math.sqrt(number)
print(square_root)
# 6
```
Example of importing the `random` library and using its `randint()` function to generate a random number between 1 and 10:
```import random

number = random.randint(1, 10)
print(number)
# random number between 1 and 10
```

### Exercise 1 of 6

Write a line of code to import the random library.

### Exercise 2 of 6

Write a line of code to import the math library.

### Exercise 3 of 6

Fix the error by entering the missing line.
```random_num = random.randint(1, 10)
```

### Exercise 4 of 6

Fix the error by entering the missing line.
```radius = 3
area = math.pi * math.pow(radius, 2)
print(f"The area is {area}")
```
