The answer is 37.68
You multiply the diameter by pi (3.14). So in this problem you multiply 12 x 3.14.
U set up x+10+60=180 u get 60 by subtracting 180 and 120
x+10+60=180
x+70=180
-70 -70
x= 110
if i'm not mistaken that's how you do it
Answer:
8
Step-by-step explanation:
-x²+ 4x - 2 = 0
x² - 4x + 2 = 0
where
<u>a = <em>1</em></u>
<u>b = -<em>4</em></u>
<u>c<em> = </em><em>2</em></u>
Now,
Diacriminant (D)
<em><u>D = b² - 4ac</u></em>
= (-4)² - 4(1)*(2)
= 16 - 8
= 8
30,000 + 6,000 + 300 + 20 + 5 + 0.7 + 0.04 + 0.001 = 36,325.741
