What’s the circumference, to this problem ?
1 answer:
Answer:
The formula to get the circumference of a circle is but in this case we see that a diameter is being used therefore we can get rid of the 2 and the r because that is what the diameter and just replace d into there like this
.
We can then input the value and we get that which then just narrows down to
.

Answer:
mBC = 96°
mB = 55°
mC = 77°
mAB = 154°
Step-by-step explanation:
The angle mB inscribes the arc mAC, so we have:
The sum of internal angles of a triangle is 180°, so in the triangle ABC we have:
Using again the property of inscribed angles, we have:
Answer:
No, -1/3 is not a solution
Step-by-step explanation:
See if it is a solution by plugging in -1/3 as v and seeing if the equation is correct:
9v - 2 = 3v
9(-1/3) - 2 = 3(-1/3)
-3 - 2 = -1
-5 = -1
-5 -1
So, since the equation is incorrect, -1/3 is not a solution.
