Answer:
188.496
Step-by-step explanation:
A=2πrh+2πr^2=
A=2·π·3·7+2·π·3^2
A= 188.49556
Rounded up because 4th decimal is a 5.
A= 188.496
2x^2+4x+2
Carry the 2 over to the 3 behind the 4 and multiply so 2times2 is 4. So i new equation is.
X^2+4x+4
Now you have to find the factors of 4 which is 1,4 and 2,2
So now you have to see which one adds up to 4 so 1+4 is 5 so cross that out and 2+2=4.
So the two number is 2 and 2 now you have to bring down the x^2 and the signs.
(X+2) (X+2) and thats your answer
9, 15, 22.
If you add any of the two side lengths, they will be greater than the third.
The answer is 6*square rooted*2
