The area of the base is:
A = root ((s-a) * (s-b) * (s-c) * (s))
Where,
a, b, c: sides of the triangle
s = (a + b + c) / 2
We have then:
s = (9 + 9 + 9) / 2
s = 13.5
A = root ((13.5-9) * (13.5-9) * (13.5-9) * (13.5))
A = 35.07
Then, the surface area of the prism is:
S.A = 2 * A + 9h + 9h + 9h
Where,
h: height of the prism:
Substituting values:
421.2 = 2 * (35.07) + 9h + 9h + 9h
Clearing h:
27h = (421.2 - 2 * (35.07))
h = (421.2 - 2 * (35.07)) / (27)
h = 13
Answer:
the height of the box is:
h = 13 inches

Answer: C- $8. Add all the ticket prices together which is 40, than divide by 5 because there are 5 theaters and you get $8.
The limit does not exist. Because its left limit when x < 0 is -9, and the right limit is 2, which is not equal.
All this is saying is: "Solve this equation for 'r': V = π r² h ."
You should be able to do that.
<span>V = π r² h
Divide each side by 'π': V / π = r² h
Divide each side by 'h': V / π h = r²
Square root each side: r = √ ( V / π h) .</span>
