Answer:

138.3ft^3

Step-by-step explanation:

Volume for cylinders : V = pi*r^2*h

Volume for cones : V = pi*r^2*(h/3)

Since we know the radius (r) is 2 and the height is 10 and 3 for the cylinder and cone respectively, all we do is plug in.

Volume for cylinder is about 125.7ft^3

Volume for cone is about 12.6ft^3

Then just add them together for a total of 138.3ft^3

Breaking down:
$\frac{3}{15} = \frac{1}{5}$
${w}^{6} \div {w}^{2} = {w}^{4}$
${v}^{5} \div v = {v}^{4}$

Therefore,
$\frac{3 {w}^{6} {v}^{5} }{15 {w}^{2}v } \\ = \frac{{w}^{4} {v}^{4} }{5}$

Hope this helps. - M

Part B : What would the math be to show how I did the math? HELP ME PLZ!!

Tresset [83]

The equation would be 55h+40=c
h-hours
40-Initial value-Price paid at start
c-total cost
so if you plug the numbers in, 55h+40=190
Subtract 40 from both sides, 55h=150
Divide both sides by 55, h=150/55
150/55=<span>2.72727272727
and that rounds to 2.73</span>
