From my understanding you ahould use the trig function cos to solve this.
cos(c) = 15/25 or 0.6
if you have this following function on your calculator I suggest using it:

cos ^{ - 1}

by using the function like so:

cos^{ - 1} (0.6

you should get about 53.13° (rounding to the nearest hundredth)
Hope this helped.

aalyn [17]

Answer:

  • Radius=50 ft
  • π=3.14
  • Height=30 ft
  • Volume=?

We know that,

\star \:  \:  \purple{Volume_{(cone)} =\pi {r}^{2}   \frac{h}{3} }

\star \:  \:  \purple{Volume_{(cone)} =3.14 \times  {(50)}^{2}  \times   \: \cancel\frac{30}{3}  \:   }

\star \:  \:   \purple{Volume_{(cone)} = 3.14 \times (50 \times 50) \times 10}

\star \:  \:  \purple{Volume_{(cone)} =3.14 \times 2500 \times 10 }

\star \:  \:  \purple{Volume_{(cone)} =78500 }

Thus,the third option is correct.
