Hi there! BF = 14
If AC = 19, the radius of circle C is 19.
In the picture we can see that AC = A F + CF.
Based on all the data we have we can fill in th: formula:
19 = A F + 12.
Subtract 12 from both sides.
7 = A F
A F = radius circle A = 7
BF, which is the diameter from circle A is two times the radius of the circle. Hence,
BF = 2 × A F = 2 × 7 = 14
~ Hope this helps you.
~ Note: there is a space between A F because the system doesn't accept is without a space (because of rude language).
50% would be the other half of the square
Answer:
<h2>Width = 7.6 ft.</h2><h2>Length = 12.7 ft.</h2>
Step-by-step explanation:
Perimeter of a rectangle (P) = 2L + 2W
where
P = 40.6 ft.
L = 2W-2.5
plugin values into the formula:
40.6 = 2(2W-2.5) + 2W
40.6 = 4W - 5 + 2W
40.6 + 5 = 6W
W = 45.6 / 6
W = 7.6 ft.
L = 2W-2.5
L = 2(7.6) - 2.5
L = 12.7 ft.
proof:
P = 2(12.7) + 2(7.6)
P = 40.6 ft.
