The radius of one sphere is twice as great as the radius of a second sphere. Find step-by-step Secondary school maths solutions and the answer to the textbook question The radius of one sphere is twice as great as the radius of a second sphere. Let's assume the radius of the second sphere is "r". te is Son estion #4 Multiple Choie 4 The radius of one sphere is twice as great as the radins of a second sphere. Therefore, if the radius of one sphere is twice the radius of another, the volume of the larger sphere would be 8 times that of the smaller one (2³ = 8). Let's call the radius of the smaller sphere "r" and the radius of the larger sphere "2r". 57 cm² while the surface area of the larger sphere, with a radius of 2 cm, would be 50. Therefore, we can express this as: R =2r 2. The surface area of a sphere is given by the formula 4πr^2. Find the ratio of their surface areas. and more. niuyyc voi ma8vmw o3pgj hcsn kdevhe 5bgxy 7h1c 0aje0a gzxt1aw
