Answer:

14. 39.0625in

15. 50.13cm

Explanation:

Start with the general equations, and define the variables.

14.

$v = \pi {r}^(2) h \\ d = 32→r = 16$

Then, fill in the values you know, and solve for the variable.

$10000\pi = \pi {(16)}^(2) h \\ 10000 = 256h \\ h = (10000)/(256) \\ h = 39.0625$

15.

Same thing:

$600000 = \pi {r}^(2) (76) \\ {r}^(2) = 2513 \\ r = √(2513) = 50.13$
