Question

the ratio of the volumes of two right circular cones of the same height and the base radii in the ratio 5:7 is

Answer 1

Vol of cone is 1/3 the volume of cynder it is made of

Answer 2

so, (1/3)(pi*r^2*h)
\[
{V_1\over V_2}={r_1^2\over r_2^2}
\]

Answer 3

(r1)^2/(r2)^2=5/7

Answer 4

25/49 is the answer

Answer 5

right
