Ex: (A) 19.95÷29.95 and you will get your answers
Answer:
(a) draw the graph using these coordinates :
(0,-1) and (3,1)
(b) x = 3
Answer:
The circle length is 90*pi which should be 3.14
So the circle length is 282.6
The central angle is 90 degree which is 1/4 part of 360 degree
From the theory of arc, the arc length should also be 1/4 part of circle length.
So the answer should be 1/4 * 282.6 = 70.65
Becasue it should be to the nearest tenth, so the answer should be 70.7
