3/8 yards.
1/2 is the same as 4/8, since 4 is 1/2 of 8. So, you just need to subtract 4/8 from 7/8 to find the remaining ribbon.
7/8 minus 4/8 is 3/8, so there would be 3/8 yards of ribbon remaining.

Step-by-step explanation:
Answer:
210.25 or 210.3495409 depending on how your teacher does it
Step-by-step explanation:
Looking for circumference of the circle when it asks for perimeter
Formula for Circumference C = π x r <em>3 (cubed)</em>
The diameter is 10 so you take half of ten or 10 ÷ 2 = 5
5 x 5 x 5 = 125 (r squared equation)
125 x π = 392.6990817
Some classes ans stuff use 3.14 for pi so i'll show it that way too
125 x 3.14 = 392.5
(equation with π)
392.6990817 ÷ 2 = 196.3495409
196.3495409 + 14 = 210.3495409
(equation with 3.14)
392.5 ÷ 2 = 196.25
14 + 196.25 = 210.25
The third and fourth options.
