Question

a milk tank is in the shape of cylinder with a hemisphere of same radii attached to both in office as shown in figure if the total height of the tank is 66 metre and the radius is 1 calculate the maximum quantity of milk in Lead in the tank in litres and also calculate the total surface area of the tank​

Answer 1

hope this helps you plz mark as brainliest plz....

Answer 2

Volume of tank=$16.762\times 1000=16762 L$

Total surface area of tank=$2\times \frac{22}{7}\times 1(4+2(1))=37.7 m^2$

Step-by-step explanation:

Height of tank=6 m

Radius of tank,r=1 m

Height of cylinderical part,h=6-(1+1)=4 m

Volume of hemisphere=$\frac{2}{3}\pi r^3$

Volume of cylinder=$\pi r^2 h$

Where $\pi=\frac{22}{7}$

Volume of tank=Volume of cylinder+2(volume of hemisphere)

Volume of tank=$\frac{22}{7}\times 1\times 4+2\times\frac{2}{3}\times \frac{22}{7}\times 1=16.762m^3$

Volume of tank=$16.762\times 1000=16762 L$

Using 1L=1000 cubic meter

Total surface area of tank=Curved surface area of cylinder+2(surface area of hemisphere)

Total surface area of tank=$2\pi rh+2(2\pi r^2)=2\pi r(h+2r)$

Total surface area of tank=$2\times \frac{22}{7}\times 1(4+2(1))=37.7 m^2$
