A ramp leading into a building makes a 15 degree angle with the ground. The end of the ramp is 10 feet from the base of the buil

stiks02 [169]

Answer:

The length of the ramp is x = AC = 10.35 feet

Step-by-step explanation:

From the ΔABC

AC = x = length of ramp

BC = 10 feet

$\theta = 15$ °

$\cos 15 = \frac{BC}{AC}$

$\cos 15 = \frac{10}{x}$

x = 10.35 feet

Therefore the length of the ramp is x = AC = 10.35 feet

DaniilM [7]

Answer:

Step-by-step explanation:

The volume of a cone is given by the formula ...

V = (1/3)πr²h

For a pile with a radius of 8.5 m and a height of 9 m, the volume is ...

V = (1/3)π(8.5 m)²(9 m) = 216.75π m³ ≈ 680.94 m³

Then the number of truckloads required to create that size pile will be ...

(680.94 m³)/(12 m³/truck) = 56.745 trucks

Even a partial truck load entails another trip, so ...

57 truck loads of sand are needed.
