Expert's answer

Solution 1:

If V(from b)=75.3 cubic feet,

b=V

Solution 2:

V(after drained) = V(tank) - V(drained) = πr

b=(V(after drained)) / (πr

If V(from b)=75.3 cubic feet,

b=V

_{b}/(πr^{2}) = 75.3/(3.14*3^{3})= 75.3/27.9=2.7 feetSolution 2:

V(after drained) = V(tank) - V(drained) = πr

^{2}*h-35.3 = 3.14*3^{2}*4-35.3=76.3 cubic feetb=(V(after drained)) / (πr

^{2}) = 76.3/ 27.9 = 2.7 feetNeed a fast expert's response?
