Step-by-step explanation:
A=πr2=π·52≈78.53982cm² (or 78.54)
78.54 x 5
Answer:

Step-by-step explanation:
We need to factor out numerator and denominator in order to simplify the rational expression by cancelling common factors.
Numerator : x^3 - 4 x = x (x^2 - 4) = x (x - 2) (x + 2)
Denominator (factoring by grouping):
x^2 - 5 x + 6 = x^2 - 3 x - 2 x + 6 = x (x - 3) - 2 (x - 3) = (x - 3) (x - 2)
Then we can cancel out the common factor (x - 2) in both numerator and denominator, leading to:
x (x + 2) / (x - 3) = (x^2 + 2)/ (x-3)

What's a hundredth?
it's like this:
0.01
so where is the hundred place in this number?
389.9<em>9</em>3
it's the 9 that i made boldface
so to round to this number we delete everything after it, asking ourselves if the number after it is 4 or less? yes! so we can just delete it without changing anyway
389.99
Answer:
360 degrees divided by that order
I think the answer is option 3.
