Answer:

Sandy needs
14.13\ ft^(2) of carpet to build a scratching post for her cats

Explanation:

Sandy needs to calculate the surface area of the cylinder

The surface area of the cylinder is equal to


SA=2\pi r^(2)+2\pi r(h)

we have


r=1/2=0.5\ ft ----> the radius is half the diameter


h=4\ ft

assume


\pi =3.14

substitute the values


SA=2(3.14)(0.5)^(2)+2(3.14)(0.5)(4)


SA=14.13\ ft^(2)

Sandy needs
14.13\ ft^(2) of carpet to build a scratching post for her cats
