A full circle is 360 degrees.
The circle is separated into 8 parts, so each arc is 1/8 of a circle, which equals: 360/8 = 45 degrees.
There are 2 45 degree arcs between B and C, so the arc from B to C = 45 x 2 = 90 degrees.
The answer is B.
B and D because there are the reverse of 67 + 38 = 105.
Hope that helps :)
My late response (haha): First, you would write a proportion.
Step 1: 2496 over 48 = x over 31
(x represents the area of the land that is not fenced).
Step 2: Cross multiply
2496 times 31 and x times 48
Step 3: Calculate
77376 = 48x
Step 4: Divide both sides by 48
77376/48 = 1612
48x/48 = x
Step 5: Write it as a sentence
The area of the land that is not fenced is 1612 squared meters.
Hope that helped! Good luck! :]
