How much steel sheet was actually used, if 112 of the steel was wasted in making the tank. Area of the tank is 87.12m2
Given : radius=2.1cm and height=4.5cmLet the actual area of steel used be x m2
Since 112 of the steel was wasted in making the tank.
Area of the steel used in tank = x−112x
⇒1112x
Area of the tank : 87.12 cm2
Now 1112x = 87.12 cm2
⇒x=87.12×1211
⇒95.04m2
The amount of steel used is 95.04 m2
