By the way, it's pi, not pie. just wanted you to know as you may lose marks in tests for spelling (but i may be wrong)
we know circumference is pi multiplied by the diameter.
the diameter is 2x the radius
we can re-arrange the first fact to get:
diameter (or 2x radius) = circumference divided by pi.
since the circumference is 24pi we can cancel off pi from the circumference (24pi) and pi.
now we have the diameter = 24
since the diameter is 2x the radius you divide both sides by 2 and get:
radius=12cm
2. The graph moves up 4 units. (See the blue line in the graph below.)
The domain is unchanged. (The function is still defined for all x.)
The range went from [0, ∞) to [4, ∞), since 4 was added to the minimum value.
What is the equation you are solving?
(3x -11) + 44 + (4x-7) = 180
3x - 11 + 44 + 4x - 7 = 180 like terms
7x +26 = 180
7x = 154
X = 22
Angle 1
3(22) -11
55
Angle 2
4(22) -7
81
So the largest angle is 81 degrees!
Hope this helps!
Brainliest is much appreciated!
