If a circle's circumference is 15 inches, what is its radius ?

$$\small{\text{ $ C=15 $\ inches $\qquad $ radius $ = \dfrac{7.5 }{\pi} $\ inches }}$$

C = 2πr     Solve this formula for r

$$\small{\text{$ r= \dfrac{C}{2\pi} $ }}$$

$$\small{\text{$ c= \dfrac{a}{46} $ }}$$

$$t = \dfrac{d}{r}$$

Find the time, in hours, that it would take Van Dyk to travel 26.2 miles if his average speed was 18 miles per hour. The time was about 1.3 hours. Round to the nearest hundredth

$$\small{\text{ $ 26.2\ \small{\text{miles}}* \dfrac{\ 1 \small{\text{ hour }} }{18 \small{\text{ miles }} } = 1.46 \small{\text{ hours }} $ }}$$
