Answer:
the answer is 12pie
Step-by-step explanation:
6mm is radius
circumference is ×2
so its 12
3) a^2+b^2=c^2
10^2+b^2=26^2
100+b^2=676
100-100+b^2=676-100
b^2=576
√b^2=√576
b=24
The rest are in the picture.
Pardon me please. My writing may look sloppy because I'm on bus
B=26-8
so the answer is b=18
