Find two radius of a circle whose area of equal to the sum of the area of two circle of radii 24cm and 7cm​

Answer»

Step-by-step EXPLANATION:

The radius of the circle is 7cm and 24 cm .

Area of SMALLER circle is

\pi {r}^{2}

= \pi \times 7

= 49\pi

Area of LARGER circle is

\pi {r}^{2}

=\pi \times {24}^{2}

= 576\pi

Area of required circle

= 576\pi + 49\pi

= 625\pi

Radius of circle is GIVEN by

\sqrt{625} = 25
