Step-by-step explanation:
All I did to solve this was do 180 which is the diameter and divide by 2
Answer:
240 is the answer
Step-by-step explanation:
Since 7y and 5y has the same variable, add them together.
7y + 5y = 12y
We get 12y, so y has to multiply 12 to get 16. I divided 16 by 12, which got me 1.3333333.
16 divide by 12 = 1.33333333
y = 1.33333333 ( 3 keeps going on )
