The area of circle is equal to the sum of the areas of two circles of radii 24 cm and 7 cm. The diameter of the new circle is 50 cm Let r cm be the radius of the new circle. Now, Area of the new circle = Area of the circle with radius 24 cm + Area of the circle with radius 7 cm Thus, we have: `πr^2 = pi"r"_1^2 + pi"r"_2^2` `=> pi"r"^2=[pixx(24)^2+pixx(7)^2]"cm"^2` `=>pi"r"^2 = [pixx576+pixx49]"cm"^2` `=>pi"r"^2 = pixx(576+49) "cm"^2` `=> "r"^2 = 625 pi "cm"^2` `=>"r"^2 = 625` `=> "r" = 25` ∴ Diameter of the new circle = (25 × 2) cm = 50 cm Is there an error in this question or solution? |
