Ответ:
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.
Ответ:
(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).
