V = π*r^2*h
(9000 in^3/min)*(10 min) = π*(72 in)^2*h
h = (90,000 in^3)/(5184π in^2) ≈ 5.5 in
Answer:

Step-by-step explanation:
-In a right triangle, the Sine of the base acute angle is usually given as:

-In ΔVWX,, VX is the opposite and WV the hypotenuse.
-Therefore, sine of ∠Wis calculated as;

Hence, sine of ∠W is given represented by the ratio
