Question

The circumference of two circles is 132 metres and 176 metres respectively. What is the difference between the area

of the larger circle and the smaller circle?​

Answer 1

Answer:

Step-by-step explanation

1. big radius =R=we get by substituting =28.025

small radius =r=we get by substituting=21.01

area of big circle =2×22/7×28.025×28.025=4936.8

area of small circle =2×22/7×21×21=2772

difference =4936.8-2772=2164.8
