r.
Since the radius is half of the diameter you would divide the diameter by 2 to get a radius of 8. You then substitute r for 6 in the formula and get the surface area.
A = 4

Answer:
Harris ate
slices of pizza.
Step-by-step explanation:
If 4 friends evenly divided up an n-slice pizza
Total Slices=n
Number of people sharing=4
Each Friend will receive
slice of pizza
Harris Ate 1 fewer slice than he received
Harris' Share= ![\dfrac{n}{4}](https://tex.z-dn.net/?f=%5Cdfrac%7Bn%7D%7B4%7D)
Number of Slices Harris Ate ate![\dfrac{n}{4}-1\\=\dfrac{n-4}{4}](https://tex.z-dn.net/?f=%5Cdfrac%7Bn%7D%7B4%7D-1%5C%5C%3D%5Cdfrac%7Bn-4%7D%7B4%7D)
