r = 2 inches

total h of the cylinder = 6+6+6 = 18 inches

$SA = 2\pi {r}^{2} + 2\pi \: rh$

$= 2\pi \: r(r + h)$

$= 2 \times 3.14 \times 2(2 + 18)$

$= 2 \times 3.14 \times 2 \times 20$

$= 251.2square \: inches$

Plz help if you can Thank ya

koban [17]

Answer:

$90\pi$

Step-by-step explanation:

The first step is to find the slant height of the cone. Using the pythagorean theorem, you can find that $\sqrt{12^2+5^2}=13$ cm. Plugging this into the equation, you get $\pi \cdot 5 \cdot 13=90\pi$ . Hope this helps!
