From the shaded diagram, Raphael will need 3 of the 6 equal portions, or exactly 1/2 of the area of the circle. Given a radius of 12 ft, knowing that the area of any given circle is

, and knowing that the area of the fabric needs to be half of the total area, we can set up the equation for the area of the fabric

:

Simplifying, we find that the area of the fabric is exactly

ft.² Using the approximation of 3.14 for π, we get an area of approximately

ft² of fabric.
(c) 1792
v1+v2
v1=64 v2=1728
64+1728=1792
Answer:
55°
Step-by-step explanation:
Since the lines are parallel angle 2 and 4 will be supplementary and we can find the angle measure using the given 125° angle. According to the angle rule of corresponding angles we can determine that angle 4 equals 55
