Question

If the perimeters of circle A and circle B are 88 m and 154 m respectively, what is the sum of their diameters? (In m)

Answer 1

Answer:

Step-by-step explanation:

Perimeter of circle A = 88 m =2*22/7*R

2*22/7*R =88

R=14m

Hence the diameter is 28 m

Perimeter of circle B=154 m=2*22/7*R2

2*22/7*R2 =154 m

R2=49/2m

Hence the diameter is 49 m

D1+ D2 = 28+49=77 m
