Answer:

  • 1473 in²

Step-by-step explanation:

<u>Surface area, including sides and the top lid:</u>

  • S = πr² + 2πrh
  • S = 3.14*7² + 2*3.14*7*30 = 1472.66 in² ≈ 1473 in² (rounded)

alukav5142 [94]
<span>The most accurate answer is Sarah's with 8,494.84 cm2. While Kevin's answer is accurate if you're using 3.14 for pi, pi is an infinite number and does not end at the 2 decimals he used.</span>

You can work out c first. That's probably the key to the whole problem.
The adjacent side to a 60o angle is 1/2 the hypotenuse
The hypotenuse in this case = 4 Sqrt(3)
Then c = 1/2 (4 sqrt(3)) 
c = 2 sqrt(3) That means d is not true.

Next work out a.
a is in the same triangle as c and the hypotenuse.
a^2 + c^2 = hypotenuse^2
a = ??
c = 2 sqrt(3)
h = 4 sqrt(3)
a^2 + (2 sqrt(3))^2 = (4 sqrt(3))^2
(sqrt(3))^2 = 3
a^2 + 4 * 3 = 16 * 3
a^2 + 12 = 48
a^2 = 48 - 12
a^2 = 36
a = 6

Now we need to work out d
The side opposite and the side adjacent  are equal when opposite a 45o angle in a right angle triangle
d = 6


The last thing to work out is be
a = 6
d = 6
c = ???

a^2 + d^2 = c^2
6^2 + 6^2 = c^2
c^2 = 72
c = sqrt(72)
c = sqrt(6*6*2)
c = 6 sqrt(2)

The answer should be B??? Check this out.
