You need to do 2y+y+10+50=180. Then you'd combine like terms to make 3y+60=180 then to get rid of the sixty subtract it from 180 to make 3y=120 then divide by three to get y by itself so 120 divided by three is 40 which makes y whisk forty. Hope this helped.

Answer:
Circumference ≈ 50.27
Area ≈ 201.06
Step-by-step explanation:
The circumference of a circle is while the area of the circle
Since the diameter is the radius multiplied by 2, the radius of the circle is 8. So substituting 8 for r, the circumference is 2 × × 8, which is approximately 50.27 (rounded to the nearest hundredth) and the area of the circle would be × 8². 8² is 64 so 64 times pi is approximately 201.06 (rounded to the nearest hundredth)
