A water tank has the shape of an inverted circular cone with base radius 4 m and height 6 m. If water is being pumped into the tank at a rate of 16 m3 /min, find the rate at which the water level is rising when the water is 3 m deep.

Step-by-step explanation:

because it is i hope this is right sorry if its wrong

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
