I don’t kno how to do any of this ...

Answer:
the first one the area is 706.86. i rounded.
Step-by-step explanation:
the equation for finding the area of a circle is
the radius squared times pi. hopefully that helps you solve the rest of them!
1: 706.86
2: 95.03
3: 12.57
4: 12.57 (?) (can't see all of the question)
5: 314
Formula for circle: A=3 x r (radius) x r (radius)
Multiply the radius times itself and multiply that by three.
