13)
Circumference (C) = 2π·r
11π = 2π·r
11/2 = r
******************************
Area (A) = π·r²
= π·(11/2)²
= 121π/4
≈ 94.985 in²
14)
diameter = 2r
42 = 2r
21 = r
*******************
Area (A) = π·r²
= π·(21)²
= 441π
≈ 1384.74 in²
***************************
$280/1384.74 in²
x = $0.20
Answer: about 20 cents per square inch
Answer:
-30
Step-by-step explanation:
To find slope, subtract two y's and then subtract the x's in the same order.
<u>12-(-18)</u>=<u>30</u>=-30
11-12 -1
You could also switch the order like this...
<u>-18-12</u>=<u>-30</u>=-30
12-11 1
As you can see, both of the ways of solving for slope resulted in -30.
Hope this helps!! Have a great day :3
The answer is 5.
Because take x=1 entry to the graph and going vertical until you intercept the curve, then read the value on the y axial
the answer is 2. see attached for step-by-step instructions. hope that helps!
Answer:
5(-3) would be the first step
Step-by-step explanation:
5 * -3 = -15
-15 + 6 = -9
-9 is the answer
