.
Step-by-step explanation: Use 3.14 for pi or if you can, use the π symbol on your calculator. Find the radius and square it, then multiply by pi.
When dividing, you can flip the second fraction and multiply the two, giving you 5x/9 * 15x^2/18, which is 25x^3/54
Answer: B
Step-by-step explanation:
The y-intercept is the number that is a constant. It is the "b" in y=mx+b. The y-intercept is the point on the y-axis. That means the x-coordinate is 0. With this information, we can automatically eliminate C and D.
Since we know y-intercept is the "b" on y=mx+b, we know that 6 is the "b" in the given equation. Therefore, B is the right answer.
