Answer:
PerimeterFigure= pi*DIameter/2= 1.5*pi ft.
Step-by-step explanation:
The perimeter is the length of the figure, since we are dealing with an semi-circle, we can use the perimeter equation for a full circle and divide it by half.
Perimeter= 2pi*R= pi*Diameter.
Since Our figure is a semi circle, as we say earlier, we now will divide the above result by half.
PerimeterFigure= pi*DIameter/2= 1.5*pi ft.
That’s hard , I don’t even know
Answer:
The top right option.
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
Together, these two angles form a flat line which is 180 degrees
(x + 7) + (4x - 52) = 180
5x - 45 = 180
+ 45 + 45
5x = 225
x = 45
