Answer:
1248' x 2056' so I think you missed copying decimals but I would asume B
Step-by-step explanation:
312''x(1/(1/4''))=1248'
514''x(1'/(1/4''))=2056'
Answer:
706.5m^2
Step-by-step explanation:
The sign is a circle
Area of a circle is (pi)r^2
d = 30 in -> r = d/2 = 30/2 = 15
Area = 3.14 x (15)^2 = 706.5m^2
The central angle corresponding to AOB is half of the 8pi/9 radians mentioned, meaning that the central angle of AOB is 4pi/9.
Converting that to degrees:
4pi/9 180 degrees
-------- * -------------------- = 80 degrees.
1 pi
(2x 6)(x-1)=0 happy to help :)
