Question

46. A circle whose radius is r сm is cut into
four equal parts as shown below. If the
perimeter of whole figure is 174 cm,
then the sum (a + b + c + d + e) is:

(A) 126 cm
(C) 70 cm
(E) None of these
(B) 140 cm
(D) 105 cm

Answer 1

Step-by-step explanation:

a, b, c, d and e are the radius of a circle there4 a=b=c=d=e=r. The perimeter of fig. is 174 CM. As perimeter of circle =circumference circumference =174. 174 = 2*22/7*r. r =27.22.. a+b+c+d+e=5r=5*27.22=136.2
