Answer:
6.28
Step-by-step explanation:
You need to find the circumference,
so 2*3.14*R
the radius is 4 so
2*3.14*4
25.12
now you have found the length of the full circle, you need to find a quater like because there is 4 90 degres in a circle
so divide you answer by 4
First, divide.
680 / 4 = $170 per TV
Second, multiply.
170 * 7 = $1,190
Best of Luck!
