Answer:

4\frac{1}{2} or 4.5 hours

Step-by-step explanation:

Total length of playlist = 6\frac{3}{4} = \dfrac{27}{4} hours

Time spent cleaning/listening = \frac{2}{3} of total length of playlist

                                                  = \dfrac{2}{3} \times \dfrac{27}{4} = \dfrac{9}{2} hours = 4\frac{1}{2} hours

Sergio039 [100]

The amount of the extra snow would a child need to take a snowball will be 636.71 cubic cm.

<h3>What is the volume of the sphere?</h3>

Let d be the diameter of the sphere.

Then the volume of the sphere will be

V = 1/6 πd³ cubic units

Then the amount of the extra snow would a child need to take a snowball with a diameter of 8 cm and increase its size to a snowball with a diameter of 12 cm will be

Amount of snow = 1/6 π x 12³ - 1/6 π x 8³

Amount of snow = 288 π - 85.33π

Amount of snow = 636.71 cubic cm

More about the volume of the sphere link is given below.

mr Goodwill [35]
The tangent ratio is
   tan(38°) = opposite/adjacent = (height of cliff)/(distance to base)
Multiplying the equation by the denominator gives
