Work Step by Step

To find the area of the tank's lid, we use the formula for the area of a circle: $A=\pi*r^{2}$. where $r=24in$ Therefore, we have: $A=\pi*(24in)^{2}=1,809.56in^{2}=1,809.56/144~ft^2=12.57ft^{2}\approx 12.6~ft^2$. where we used the fact that there are 144 square inches in one square foot.
