Question

find the perimeter of the following image

Answer 1

perimeter of this image is :-
total Circumfernece of circle - 1/4 circumference of circle + 2*radius
2πr - 1/4 *2πr + 2*5.6
2*22/7 *5.6 - 1/4 *2 * 22/7 * 5.6 + 11.2
246.4/7 - 246.4/4*7 + 11.2
35.2 - 8.8 +11.2
26.4 + 11.2
37.6 unit

Answer 2

draw complete the circle  join the points and mark it as AB chord

find the  length of chord by using Pythagoras taking triangle AOB

angle O =90

AO =5.6cm

perimeter = perimeter of circle -  ar minor segment

                  =  2*22/7 *5.6 - area of quadrant - area of triangle

i couldn't do all the calculations right now  but this is basically the solution just put the values

let me know if it was helpful or else i'll try to find the answer
