When converting English phrases into mathematical expressions/equations, we do things from left to right. That is why it's 4 - 20 instead of 20 - 4.

This rule is applied to division as well.

The bicycle with a 30-inches diameter rolls approximately 28.8 more than a tire with the diameter with 21-inches.

<u><em>How to solve:</em></u>

  • First use the formula: C = 3.14d
  • Replace the d value with 30 and solve the equation:

C = 3.14 x 30    ⇒   94.2477796077

  • Then solve the equation again but 21 as the d value:

C = 3.14 x 21     ⇒   65.9734457254

  • Then subtract 65.9734457254 from 94.2477796077 to get the approx. answer of 28.8
