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
25% is .25 as a decimal 100*.25=25 so 25% of 100 is equal to 25 because, 25% goes into 100% 4 times so we immediately know that where looking for a number that can go into 100 4 times and it just so happens that 25=25 is true and 100=100 is true so are answer is literally in the question.
