Answer:

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

Step-by-step 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
