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
Check the picture below.
now, keep in mind that ship B is going at 20kph, thus from noon to 4pm, is 4 hours, so it has travelled by then 20 * 4 or 80 kilometers, thus b = 80.
whilst the ship B is moving north, the distance "a" is not really changing, and thus is a constant, that matters because the derivative of a constant is 0.
Answer:
I think the answer is Step 2, 12x − 16 = 16 + 4x
plz mark me as brainliest if i was right :)
Answer:
Hi there!
Your answer is:
$440 earned from working a 50 hour week
Step-by-step explanation:
8× 40= $320
Subtract 40 from 50 to determine how many overtime hours he worked!
12× 10 = $120
320+ 120= $440
I hope this helps!
