Answer:
301.6 ft³
Step-by-step explanation:
The volume (V) of a cone is calculated using the formula
V =
× area of base × perpendicular height (h)
h can be calculated by using Pythagoras' identity in the right triangle
with hypotenuse = 10 and legs 6 and h, thus
h² + 6² = 10²
h² + 36 = 100 ( subtract 36 from both sides )
h² = 64 ( take the square root of both sides )
h =
= 8
Hence
V =
× π × 6² × 8
=
× 288π =
≈ 301.6
It would be easier to translate this into mathematical terms first.
Let n = the unknown number
6n <span>> n + 20
Subtracting both sides by n to simplify:
6n - n </span><span>> n + 20 - n
</span>5n <span>> 20
</span><span>
Dividing both sides by 5:
5n/5 </span><span>> 20/5
</span>n <span>> 4
</span><span>
Among the choices, the correct one is the second choice.
