The diameter of a circle whose area is equal to the sum of the areas of the two circles of radii 24 cm and 7 cm is ______.
The diameter of a circle whose area is equal to the sum of the areas of the two circles of radii 24 cm and 7 cm is 50 cm.
Let, r1 = 24 cm
r2 = 7 cm
Area of first circle = `pir_1^2`
= `576 pi cm^2`
Area of second circle = `pir_2^2`
= `49 pi cm^2`
Area of circle = Area of first circle + Area of second circle
`piR^2 = 576pi + 49pi`
R = 25 cm
Required diameter of circle = `2 xx 25`
= 50 cm
