B
36 is the radius so
The formula for circumference is radius times two and take that answer times pi
So 36×2 is 72 and 72 times pi is 226.194671058
Answer:
this is called AP arithmetic progression
2, 4, 6.........
sn=n/2(2a+(n-1)d)
S27=





=756
Step-by-step explanation:
y=2x+1
(-0.8; -0.6)
(x, y)
-0.6=2×(-0.8)+1
-0.6=-0.6
it's true
y=-3x-3
-0.6=-3×(-0.8)-3
-0.6=-5.4
it's not true
i hope you have understood how to do this exercise, so you can do B
Answer:
y = -2x + 4
Step-by-step explanation:
First find slope:


We know equation of a line is y = mx + b, where m = slope and b = y-intercept, so we can plug in the slope:
y = -2x + b
The y-intercept of the equation is 4 because the coordinate (0, 4) is given. Therefore, the equation is:
y = -2x + 4
Answer:
SAS
Step-by-step explanation:
Triangles QRS and TRS share the same side which is congruent by the reflexive property and perpendicular angles. They also have another congruent leg as marked on the diagram. These forms side-angle-side or SAS.
