See, the area of paper pieces given is : r^3

So, divide the full area by this area to get the answer..

Divide it:

$$\huge \frac{150r^2}{r^3}$$

thank you

anonymous · Answer

how would you divide that with r2

anonymous · Answer

$$\huge = \frac{150 \cancel{r} * \cancel{r}}{\cancel{r}*\cancel{r} * r}$$

anonymous · Answer

so its 150 over r

anonymous · Answer

Yes..
