What the hell is this they didn’t teach me this help me

Answer:
C
Step-by-step explanation:
Area = π[tex]r^{2}[/tex]
r means radius
radius = d/2
d = diameter
8 /2 = 4
4 is radius
[tex]4^{2}[/tex] = 16
^ ( its 4 x 4 ) ^
so then,
Area = 16π
Answer:
Step-by-step explanation:
[tex]A=\pi r^2,\ r=\frac{d}{2}\\ \\ A=\frac{\pi d^2}{4},\ d=8cm\\ \\ A=\frac{64\pi}{4}\\ \\ A=16\pi cm^2[/tex]
