in a circle of radius 28 cm, an subtends an angle of 45° at the centre, then find the length of the arc(in cm)​

22cm

Step-by-step explanation:

Length of arc = * 2r

                      = * 2 * * 28

                      = 22 cm

he kicked it up? is this the answer ?

step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
