Grain is falling from a chute onto the ground, forming a conical pile whose diameter is always three times its height. how high
bezimeni [28]

Given that grain is falling from a chute onto the ground, forming a conical pile whose diameter is always three times its height.

So if D is the diameter and h is the height of the conical pile then we can write:


D=3h

We know that diameter = 2r, where r is the radius

2r=3h

r=\frac{3h}{2}

Volume of conical pile is given by formula

V=\frac{1}{3}\pi r^2h

Given that volume is 1110 cubic feet.

Now plug the values of Volume and r into equation of volume

1110=\frac{1}{3}\pi (\frac{3h}{2})^2h

1110=\frac{1}{3}\pi\cdot\frac{9h^2}{4}\cdot h

1110=\pi\cdot\frac{3h^3}{4}

1110\cdot\frac{4}{3\pi}=h^3

471.098631552=h^3

take cube root of both sides

7.78103342467=h

Hence height is approx 7.78 feet.

Chandler is walking 1/16 km every 10 minutes. How many kilometers will he walk in 1 hour?!
SashulF [63]

Answer:

\frac{3}{8} or\ 0.375\ km

Step-by-step explanation:

Given: Chandler walk 1/16 km every 10 minutes.

First, lets find how many 10 minutes in one hours or convert minutes in hours.

∴ Time= \frac{60}{10} \ h

Now, finding kilometres travelled in 1 hour.

Distance travelled= \frac{1}{16} \times \frac{60}{10} = \frac{1}{16} \times 6

Distance travelled = \frac{3}{8}

Converting \frac{3}{8} \ km into decimal will have 0.375 km.

∴ \frac{3}{8} or\ 0.375\ km will chandler walk in 1 hour.
