Question

The ratio of the area of two circle are 100:49. Then the ratio of their radii would be

Answer 1

Answer:

Area of 1st circle = pi* r² ……..(1) r is radius

Area of 1st circle = pi* r² ……..(1) r is radiusArea of 2nd circle = pi * s²………(2) s is radius

Area of 1st circle = pi* r² ……..(1) r is radiusArea of 2nd circle = pi * s²………(2) s is radius(1) /(2) =

Area of 1st circle = pi* r² ……..(1) r is radiusArea of 2nd circle = pi * s²………(2) s is radius(1) /(2) =(Pi*r²) / (pi* s²) = 49/64

Area of 1st circle = pi* r² ……..(1) r is radiusArea of 2nd circle = pi * s²………(2) s is radius(1) /(2) =(Pi*r²) / (pi* s²) = 49/64=> r² /s² = 49/64

Area of 1st circle = pi* r² ……..(1) r is radiusArea of 2nd circle = pi * s²………(2) s is radius(1) /(2) =(Pi*r²) / (pi* s²) = 49/64=> r² /s² = 49/64= r/s = 7/8 ……….(3)

Area of 1st circle = pi* r² ……..(1) r is radiusArea of 2nd circle = pi * s²………(2) s is radius(1) /(2) =(Pi*r²) / (pi* s²) = 49/64=> r² /s² = 49/64= r/s = 7/8 ……….(3)Now, circumference of 1st circle = 2* pi* r

Area of 1st circle = pi* r² ……..(1) r is radiusArea of 2nd circle = pi * s²………(2) s is radius(1) /(2) =(Pi*r²) / (pi* s²) = 49/64=> r² /s² = 49/64= r/s = 7/8 ……….(3)Now, circumference of 1st circle = 2* pi* rcircumference of 2nd circle = 2*pi*s

Area of 1st circle = pi* r² ……..(1) r is radiusArea of 2nd circle = pi * s²………(2) s is radius(1) /(2) =(Pi*r²) / (pi* s²) = 49/64=> r² /s² = 49/64= r/s = 7/8 ……….(3)Now, circumference of 1st circle = 2* pi* rcircumference of 2nd circle = 2*pi*s=>( 2* pi*r) / (2* pi*s)

Area of 1st circle = pi* r² ……..(1) r is radiusArea of 2nd circle = pi * s²………(2) s is radius(1) /(2) =(Pi*r²) / (pi* s²) = 49/64=> r² /s² = 49/64= r/s = 7/8 ……….(3)Now, circumference of 1st circle = 2* pi* rcircumference of 2nd circle = 2*pi*s=>( 2* pi*r) / (2* pi*s)= r/s = 7/8 ……… ANS
