Answer:
8483 ft²
Step-by-step explanation:
Subtract the area of the smaller circle from the area of the greater circle
Greater Circle area:
πr² = π × 140²
= 61583.2 ft²
Smaller Circle area:
= π × 130²
= 53099.8 ft²
Area of track:
61583.2 - 53099.8 = 8483.4ft²
= 8483ft² (to the nearest ft²)
Answer:
6
Step-by-step explanation:
Answer:

Step-by-step explanation:
Find the slope using the slope formula:
, m=4
Use any set of points you know to solve for b. (2, 0)
Pug in everything you know: 0=4(2)+b
You get: 0=8+b
Subtract 8 to get the b by itself. b=-8.
Now just plug in and you'll get the answer!
