The scale is a representation of what the drawing is to real life. The drawing will tend to be represented by a fixed figure such as 1 cm. In this case for every cm of drawing it is a representation of 8 millimetres in real life, therefore the drawing is bigger than the object.
A=24.56
Work circle= 3.14 times 4 Sq/4= 12.56
Trapezoid= 1/2 (4)(2+4)
B.16.75
OR 12.28+ Sq rt of 20
The answer to this is C. (28,10) and (22,2).
Answer: Choice B) 128
Explanation:
We'll add up the given arc measures and then cut the result in half to get the angle formed by the intersecting chords (that subtend the arcs in question).
chord angle = (arc1+arc2)/2
x = (54+202)/2
x = 256/2
x = 128
