Question

Determine areas of incircle and circumcirle of square of side 20cm .verify that area of the circumcirle is twice that of the incircle

Answer 1

Answer:Let the side of the square be x. Then, its diagonal = 2x2=2x  

Radius of incircle = x2  

Radius of circum circle= 2×x2=x2  

Required ratio = πx24:πx22=14:12=1:2
