Answer:
The formula to determine the circumference is: 2 x 3.14 x radius. All you need to do is plug in the value of the radius, 56, and multiply it by 2 and 3.14.
Step-by-step explanation:
Answer:
(2,-7)
Step-by-step explanation:
I think its that
3x + (-2x) would be just subtracting 2x from 3x, so it would be 1x or x. Hope this helped<3
Equation parallel to y = -x is y=-x+k
so 4.5 = -7 + k so k - 11.5
Equation is y = -x + 11.5
1 cubic meter = 100 cm * 100 cm * 100 cm = 1 x 10^6 cc
1 kilogram = 1,000 grams
13.6 g / cc
If we had a cubic meter of mercury, its mass would be (or it would "weigh") 13.6 * 1,000,000 = 13,600,000 grams or 13,600 kilograms.
And so its density would be 13,600 kg / cubic meter.
