18.84 because circumference is 2piR so 2(3)(3.14)= 18.84
They won 96 games because 160 divided by 5 is 32. now 32 times 3 equals to 96. :) Hope this helps
Equalizw the denominators so that the nominators will be equal in this wat sonyou can find the value of x if you want i can solve it
Y= -7.5 that is the answer youre welcome
You can eliminate 81 because we know 
The dot is on approximately 9.32 (my estimate) so I would square that number:
(9.32)² = 86.8624 so if you round this you get 87
