3. Write a procedure that converts degrees Celsius to degrees Fahrenheit
as shown below. Have the script round the answer to the nearest inte-
ger. Test your procedure for different temperatures. (Hint: °F = (9 / 5)
× °C + 32.)

4. Write a procedure to create the house shown
on the right. Start by writing small proce-
dures that draw small parts of the house (for
example, door, roof, windows, and so on).
Then combine these procedures to create
the entire house.
5. Write a procedure to compute the area of
2
a circle (A = πr ) given its radius, as shown
below. Use π = 3.14.

PressureUnder 6. In this exercise, you’ll simulate the pressure experienced by fish under
Water_ water. Assume that the pressure P (in atmospheres) felt by a fish is
NoSolution .sb2 related to its depth d (in meters from the surface) by the relation:
P = 0.1d + 1. PressureUnderWater_NoSolution.sb2 contains a partial imple-
mentation of this simulation. Finish the script so that the fish says the
pressure it feels while swimming, as illustrated below:
