The work for these problems should be set up by the following steps.
1. Write the formula.
2. Substitute numbers for the appropriate variables. (Note: When the units are different, change
to the smaller unit.)
3. Do the calculation. For problems involving circles, express the answer in terms of  .
4. Label the answer with a unit measure.
5. You may use a calculator, but only convert to decimals on word problems. (use  = 3.14
when necessary). Round calculator answers to 2 decimal places.
