Question

Eight points p1p2............P8 divide the circle into 8 equal arcs. Measure of is

Answer 1

Answer:

Step-by-step explanation:

Angle of complete circle is 360 degree;

And the circumference of circle is 2$\pi$ R [R is the radius];

With the eight points p1, p2..... p8 the circumference is divide into eight equal parts in terms of arc as well as in term of angle of 360/8 = 45 degree:

Arc length is = 2$\pi$.R / 8

Answer 2

Answer:

Eight points p1p2............P8 divide the circle into 8 equal arcs. Measure of angle by any arc at center = 45°

Step-by-step explanation:

Complete circle = 360°

Let say angle by one arc created at center = x°

as all arcs equal

so sum of angles of all the angles by arcs = 8x°

8x° = 360°

=> x° = 45°

so Measure of angle by any arc at center = 45°

length of arc = ( 45°/360°) * 2πR = πR/4
