Work out the circumference of this circle.
Take it to be 3.142 and give your answer to 1 decimal place.
9m

C = 28.278  m

Step-by-step explanation:

The attached figure shows a circle whose diameter is 9 m.

Radius = Diameter/2

r = 9/2 = 4.5 m

The circumferance of the circle is given by :

C = 2πr

Put r = 4.5 m in the above formula

C = 2 × 3.142 × 4.5

= 28.278  m

So, the circumference of this circle is 28.278  m.

(3,0) and (0,6)

Step-by-step explanation:

(x,y) is the only way to make ordered pair.

The x was a 3 so you could cross out the first and last because they put the 3 in the y spot. When is should be (3,0).

Then the y was 6 and that I would be (0,6) so the third would also be crossed out because they put the 6 in the y spot.

So the answer is (3,0) and (0,6).
