Answer:

r = √(3V/(πh))
r ≈ 1.78 cm

Step-by-step explanation:

Multiply by the inverse of the coefficient of r², then take the square root.

$V=\dfrac{1}{3}\pi r^2h\\\\V=\dfrac{\pi h}{3}r^2\\\\r^2=\dfrac{3V}{\pi h}\\\\\boxed{r=\sqrt{\dfrac{3V}{\pi h}}}$

For V=50, h=15, this is ...

${r=\sqrt{\dfrac{3(50)}{\pi(15)}}=\sqrt{\dfrac{10}{\pi}}\approx\boxed{1.78\quad\text{cm}}$

Answer:

$14,747 at 9%
$12,129 at 5%

Step-by-step explanation:

Let x represent the amount invested at 9%. Then the difference in interest amounts is ...

(9%)x -(5%)(26876 -x) = 720.78 . . . . . assuming a 1-year investment

0.14x -1343.80 = 720.78 . . . . . . . . . simplify

0.14x = 2064.58 . . . . . . . . . . . . . . add 1343.80

x = 14,747 . . . . . . . . . . . . . . . . divide by 0.14

$14,747 is invested at 9%; $12,129 is invested at 5%.
