The answer to this question is not one of your answer choices, but the answer is 240.1413932 square centimeters.
Step-by-step explanation:
A=πr(r+√h² + r²) [radical wrapped around h² + r²]
Your answer would be (4, 16) :)

From the diagram you can see that we have constructed a right triangle, with height A and base 15.
Length of shadow = 15 feet.
Height of flagpole = A.
We know the angle of elevation is
40
∘
. Using this angle and the tangent ratio, we can find A.
tan
(
40
∘
)
=
opposite
adjacent
=
A
15
∴
tan
(
40
∘
)
=
A
15
Rearranging:
A
=
15
tan
(
40
∘
)
By calculator:
A
=
12.59

X>6 it makes me type longer but yea hope it helps
Well since the for formula for these are b × h. We are gonna do...
5 × 9 which equals 45. So your answer is 45 cubic inches
hope this helps!
