Answer:
The length of DB is 8
Step-by-step explanation:
I know it doesn't look EXACTLY like the one in the diagram but I just followed the measurements provided
1) To create an equation with r isolated, you divide both sides by π and square root both (it is given that all variables are positive). The equation is √A/π = r.
2) Plugging in the numbers give us <em>√54/(22/7) = r</em>.
√54(22/7) can be rewritten as √54*7/22, which is √378/22, which can be simplified to √189/11, or about 17.18.
The histogram that represents the data with the largest spread is Data Set B
8 pounds * 16 ounces/pound * 1 steak/4 ounces = 32 steaks
8 * 16 * 1/4 = 32
8 pounds * $4.50/pound = $36.00
8 * 4.5 = 36
$ / steak:
$36.00 / 32 steaks = $1.125/steak
That's a really good deal ;)
The formula required is tangent
