Question

the radius of circle is 3 more than the radius of 1st circle the sum of area of circle is 89\pim2 finde the radius of circle

Answer 1

let the radius of smaller circle=x

and bigger circle is 3x (given)

sum of area=89ms2

3.14*x^2+3.14*(3x)^2=89

3.14(x^2+9x^2)=89

3.14(10x^2)=89

31.4x^2=89

x=1.64

radius = 1.64

and 4.92
