1) Find the radius of the circle. You can do that by inspection; no work required.
2) Use the "area of a circle" formula A = pi r^2 to calculate the area.
3) Round off your area calculation to the nearest hundredth.
If you add the same number together it is impossible for it to be a negative number
Answer:
○ C. The lines are perpendicular.
Step-by-step explanation:
In order for equations to be perpendicular, their <em>rate of changes</em> [<em>slopes</em>] must be OPPOSITE <em>MULTIPLICATIVE</em><em> </em><em>INVERSES</em>, which in this case is so:
− to +}
> OPPOSITE
+ to −}
MULTIPLICATIVE INVERSE [RECIPROCAL]

Answer:
increase in percent
Step-by-step explanation:
it is increase in percent, but the question you're asking is dependend on the context..
Evaluate:
First you calculate the exponent:

27 + 1 <span>⋅ 9 + 12
</span>Then you multiply and divide left to right: 1 <span>⋅ 9 = 9
27+ 9 + 12
Then add and subtract:
27 + 9 + 12 = 48
So the answer to this is 48.
