Find the volume of a cone with radius 30 in and slant height 50 in. A. 3769.91 in3 B. 3768 in3 C. 113040 in3 D. 37699.11 in3
the volume of a cone is given by \[V = \frac{ 1 }{ 3 }\pi r^2h\]
r = 30 is given to us but h will need to be calculated using the pythagorean theorem
so...what's the answer? I tried it and it doesn't give me the correct answer.
maybe you made a mistake in calculating h. using pythagorean theorem... \[50^2 = h^2 + 30^2\] h should then equal \[h = \sqrt{50^2 - 30^2}\]
from here you just need to plug the numbers into a calculator
I don't have a calculator -_-
programs -> accessories -> calculator
