Answer:

324π

Step-by-step explanation:

Total Surface Area of a cone =πrl+πr²

πx 12 x 15 + π x (12²)

180π + 144π = 324π

Hi... So for this homework question It says " Amy bought 2 and 1/2 gallons of paint for $60. What is the cost for 1 gallon of pa

andrey2020 [161]

I'm sorry but the solution you proposed was a bit hard to follow, so I'll just post my solution: we convert "2 and 1/2" to a single fraction:

$2+\dfrac{1}{2} = \dfrac{4}{2}+\dfrac{1}{2}=\dfrac{5}{2}$

So, we know that 5/2 gallons cost 60 dollars, which means

$\dfrac{5}{2}g=60$

To find the cost of a single gallon, we have to solve the equation for g:

$g = 60\cdot \dfrac{2}{5} = 24$

A tin man has a head that is a cylinder with a cone on top. The height of the cylinder is 12 inches and the height of the cone i

boyakko [2]

First find the volume of the cylinder, then the volume of the cone, and after you can add the two volumes.

Cylinder:
V = π r^2 h
h = 12 inches
r = 4 inches
V = π(4^2)(12)
V = 192π

Cone:
V = 1/3 π r^2 h
h = 6 inches
r = 4 inches
V = 1/3 π (4^2)(6)
V = 32π

Now adding the two volumes, 192π + 32π = 224π cubic inches
