Answer:
72.2566311
Step-by-step explanation:
Circumference = 2πr
We don't have the radius, but we do know that half of the diameter is the radius, so 23/2 = 11.5. r = 11.5
Now, plug the radius into the equation:
2π(11.5)
Solve:
2π(11.5) = 72.2566311
Answer:
A. X + Y
Step-by-step explanation:
From this question x = -2 and y = -5
We are to find out the expression that would give a negative value.
X+Y
(-2)+(-5)
+(-) gives a negative sign. So we have
= -2-5
= -7
For x - y
(-2) - (-5)
-(-) = positive
= -2 + 5
= 3.
For [x][y]
= (-2) x (-5)
= 10
since a negative sign multiplied with another negative sign gives a positive result
For X/Y
= -2/-5
= 2/5 the result here is positive because 2 negative signs when divided cancel out.
Therefore the answer is option A since it's result is negative. Others are positive
A triangle is 180 degrees, so if you do 180-34 is should equal 146, so b + c = 146°
The arcs have to intersect to give a point which will connect to the vertex of the angle that you are bisecting.
I think the point (4,60) represent the velocity
as the velocity at this point = distance / time
so v= 15 km/h
