Answer:910
Step-by-step explanation: it rounds up because if the last number is more than 5 you round up
You do 12 time 2 the 8 times 2 and you can add 15 and 10 and the subtract
I’m guessing 8 is the radius so the formula is 2pi(r)
And when you plug in 8 into r you have 2pi(8)
When you solve it you should get 50.24
