circumference of circle= 2x3.14r
1) radius is 9
2x3.14x9
18x3.14= 56.52
2) radius is 8
2x3.14x8
16x3.14= 50.24
3) radius is 5
2x3.14x5
10x3.14= 31.4
Density = Mass / Volume = 2000/0.5
Density = 4000 Kg/m^3
Answer:
<em>0.6 ÷ 0.3 - Option 2.</em>
<em>0.2 × 0.9 - Option 3.</em>
Although x ² and x both have the variable x, you can’t add them together. So x + x + x + x is 4x and we just leave x ² the same. So the simplified expression is x ² + 4x. I hope this helped!!
Answer:
Step-by-step explanation:
First, plot the point (2, -3) on the graph. Then, use the slope to pick another point. The slope is rise over run. For your slope, the line will go 3 places up and then 4 places to the right. Using a straight-edge, follow the points and you will get the graph of the line.
