Brainliest?!?!?!?
The formula for an area of a circle is
A=pi times radius squared
there for you do pi times 9.5 to the power of two/squared (radius is half of the diameter so 19 divided by 2 is 9.5)
pi times 9.5 squared
= 283.5
I rounded to the nearest tenths

break it down, 100% of 40 is 40, and 75% of 40 is 30, so add 40 and 30 to get 70
Answer:
x=-3
Step-by-step explanation:
If x=-3, then
x³+x²-2x+12=-27+9+6+12=-27+27=0
If this is true, then x+3 is a factor. So:
x³+x²-2x+12/x+3=x²-2x+4
So the factors of x³+x²-2x+12 are:
(x+3)(x²-2x+4)
((x²-2x+4) has no real roots)........
