Mathematics

Ellis will need 244.92 ft2 of paint.

Step-by-step explanation:

First we need to find the surface area of one fencepost.

The fencepost is cylindrical, so the surface area is given by the equation:

$S = 2*\pi*r(r+h)$

If the height of the fencepost is 6 feet and the radius is 0.5 feet, we have:

$S = 2*\pi*0.5(0.5+6)$

$S =20.41\ ft^2$

The surface area of the 12 fenceposts is:

$12*S =12*20.41 = 244.92\ ft^2$

Ellis will need 244.92 ft2 of paint.
