Question

5. Find the volume of the right cone.


1360 cm^3

2260 cm^3

6790 cm^3

3390 cm^3

Answer 1

1360

Answer 2

slant hieght is root of (x^2+12^2) = 225
225-144=81
so hieght is 9cm

Answer 3

\[ V_{cone} = \frac{1}{3}\pi r^{2} h \]
\[ a^{2} + b^{2} = c^{2} \]

r = 12, h^2 + 12^2 = 15^2; for h
h^2 = 15^2 - 12^2
h = sqrt(15^2 - 12^2)

Answer 4

volume is 1/3*pi*144*9
= 1359.6 = 1360cm^3
