Question

find the radius of a circle whose area is equal to the sum of the areas of two circles whose radii are 35 cm and 42 CM respectively​

Answer 1

Answer:

area

Step-by-step explanation:

area of circle= pie r^2

so area of both circle= 22/7 (35)^2+22/7

42^2

so 22/7(35^2+42^2)=the area of bigger circle

let radius of bigger circle is R

so 22/7R^2 =22/7(35^2+42^2)

now u can find these answers
