Circumference = 2 pi r
2 pi r = 200
r = 100 / pi
Area of base = pi r r
Area of base = 100*100 / pi
Area of base = 3183.1 sq. m.
So you have to simplify
(9 x 10 x 18) 2 + (5 x 10 x 18) (-7) + (5 x 9 x 18)
(-11) + (5 x 9 x 10)
5 x 9 x 10 x 18
1620 x 2 + 900 (-7) + 810(-11) + 450 x 5
x 5 x 9 x 10 x 18
The answer would be -6/5
Answer:

Step-by-step explanation:
log(x) is the inverse function of an exponent. "log base 8 of xyz" means "what number do I have to raise 8 to, to get xyz". In this case, it means, "what number do I have to raise 8 to, to get x + 1". That's simple, it's just x + 1!

I'm guessing ill look it up later in a dictionary, if its wrong, report the answer.
Answer:
x = -16.
Step-by-step explanation:
x/-4 - (-8) = 12
x/-4 + 8 = 12
x/-4 = 12 - 8
x/-4 = 4
Cross multiply:
x = -4 * 4
x = -16.
