Webb21 aug. 2024 · Explanation: Given, the radius of a sphere is 2r. The volume of a sphere = (4/3) × (radius)3 Thus, the volume of the given sphere = (4/3) × π × (2r)3 = (4/3) × π × 8 × … WebbThe volume of the pyramids is: 8 ⋅ 1 3r2 ⋅ r = 8 3r3, and then we can calculate that the bicylinder volume is (2r)3 − 8 3r3 = 16 3 r3. Finally, using the ratio of the volumes of the bicylinder and the sphere from above, the sphere's volume is π 416 3 r3 = 4π 3 r3. Now you can see that 3 is from the pyramids and 4 is from the cube!
Webb24 sep. 2015 · Let the ratio of height to radius be ρ, then h = ρ r. The volume of the cylinder is V = π r 2 h = π ρ r 3. The surface area of the cylinder with closed ends is A = 2 π r h + 2 π r 2 = 2 π ρ r 2 + 2 π r 2 = 2 π r 2 ( 1 + ρ) hence r = A 2 π ( 1 + ρ) So the problem is now to find ρ which maximises the volume: V ( ρ) = π ρ ( A 2 π ( 1 + ρ)) 3 / 2 WebbIf the radius of a sphere is 2r, then its volume will be: A) 4 3πr3 B) 4πr3 C) 8 3πr3 D) 32 3πr3 Solution The answer is D.

The area of a sphere is always expressed in square units, like m 2, in 2, cm 2, yd 2, etc. The volume of a sphere is the total amount of capacity immersed in a sphere that can be calculated using the volume formula for the sphere which is V = (4/3)πr 3. cisplatin injection 50mgWebbThe correct option is D 8 timesInitial radius = rFinal radius = 2rInitial Volume = 4 3πr3Final volume = 4 3π(2r)3Ratio will be equal toFinal Volume Initial Volume = 4 3π(2r)3 4 3πr3 = 8. Suggest Corrections. 1. diamond\\u0027s 5kWebbThe radius of a sphere is 2r, then its volume will be Answer: (D) (32πr3)/3 Explanation: Given, the radius of a sphere is 2r. The volume of a sphere = (4/3) × (radius)3 Thus, the volume of the given sphere = (4/3) × π × (2r)3 = (4/3) × π × 8 × r3 = (32 π r3/3) Hence, option D is the correct answer.
