Answer:
2√(5/π) ≈ 2.523
Step-by-step explanation:
The radius can be found using the area formula:
A = πr²
20 = πr² . . . . . fill in the given value
20/π = r² . . . . . divide by π
√(20/π) = r = 2√(5/π) . . . take the square root and simplify
You can use your calculator to find a numerical value for this:
r = 2√(5/π) ≈ 2.52313
_____
<em>Comment on the form of the answer</em>
Radicals are often considered to be in simplest form when they do not contain fractions or square factors. Here, the "simpler" form would be ...
r = (2/π)√(5π)
involving the irrational number π in two calculations. My preference for evaluating the expression for r is to leave it as √(20/π) or 2√(5/π).
Answer:
the first one is y=x-1/2 and the second one is y=-3x+1
Step-by-step explanation:
<span>-x - 6y < 19.
Point ( -1, -3) </span>⇔ x = -1 , y = -3
<span>instead of the variables you need to put the values of x and y ( coordinates of the point )</span>
- (-1) - 6*(-3) < 19
<span>we calculate
1 + 18 < 19 </span><span>record turns mushy
Proposal
</span>the point does not belong to the graph<span>
</span>
3 hours is longer than 175 minutes. An hour is 60 minutes long, so just multiply that by 3 and compare your answer to 175.
60 x 3 = 180
180 > 175
Therefore, 3 hours is longer than 175 minutes.
Hope this helps!
