<span>the question does not have the options, but this does not limit its resolution </span> we know that volume of the cone=(1/3)*pi*r²*h where r is the radius of the cone h is the height of the cone r=12 ft Volume=1506.96 ft³ h=?
clear the variable h v=(1/3)*pi*r²*h-----> multiply by 3 3*v=pi*r²*h----> divided by (pi*r²) h=3*v/(pi*r²)------> h=3*1506.96/(pi*12²)----> h=9.99 ft---> h=10 ft
