Question

In circle P, what is the measure of AB

Answer 1

Line AC is the diameter and angle APB is a right angle

Answer 2

Is the 128 the length of AP or the length of AC or is it the angle APD?

Answer 3

its AD=128 degrees

Answer 4

2*pi*r*360/360= circumstances of circle =2*pi*r
2*pi*r*180/360=length of half circle=pi*r
2*pi*r*90/360=length of quarter=pi*r/2
2*pi*r*angle/360=length of arc corresponding to the angle..

Answer 5

what is the radius or diameter

Answer 6

what is the length of radius or diameter

Answer 7

it only gives AC as the diameter but does not give a number for it

Answer 8

2*pi*r*90/360=length of quarter=pi*r/2=pi*AP/2=pi*PC/2

Answer 9

but i dont know the radius inorder to do that
