Am stuck on this question and show your working please.

1. Calculate the circumference of a circle with a radius of 3cm.

2. A circle with a radius of 10cm has a circumference of...?

3. Calculate a circumference of a circle with a diameter of 13cm.

4. A circle has a diameter of 9.5cm.What is the distance around the circle?

5. How do you calculate the circumference of a circle?

7. When would you use 2nr?

8. When would you use nd?

9. Come up with your own examples(at least two) to show how to calculate the circumference of a circle.

1. 6pi or 18.84cm

2. 20pi or 62.8cm

3. 13pi or 40.82cm

4. 9.5pi or 29.83cm

5. You calculate the circumference of a circle with the expression 2pi(r). r stands for the radius. You can also use pi(d), or pi x diameter.

7. You would use 2pi(r) to find the circumference of a circle when given the value of the circle's radius.

8. You would use pi(d) to find the circumference of a circle when given the value of the circle's diameter.

Point Slope for is Y=MX+B
M being the slope and B is the Y intercept
The slope is given which is 5
Y=5X+B
Now lets plug in the points (2,6) (X,Y)
6=10+B
B=-4
Y=5x-4
Now lets look at our answers
A. Y=5(X-2)+6
B. Y=5(x+6)-2
Lets expand these
A. Y=5x-4
B.Y=5x+28
The answer is A
