Jan 26, 2015 · Surface area of sphere . Given: The “volume of the sphere” is 4851 cubic metres. To find: The “surface area of the sphere”. Answer: A “sphere” is a 3 dimensional geometry with a perfect round. It can be characterised from the midpoint of the sphere as the radius.
Aug 29, 2017 · Sphere: A sphere is a three dimensional figure which is made up of all points in the space which lie at a constant distance from a fixed point called the centre of the sphere and a constant distance is called its radius. Surface area of sphere: For a sphere of radius 'r' ,the surface area is given by. Surface area of sphere=4πr² sq units.
Dec 6, 2016 · Surface Area of Sphere = 4πr² 4πr² = 100 (Original area) 4πR² = 121 (Area after increase of 21 %) r²/R² = 100/121 r/R = 10/11 Now, increased value of radius in percentage. 11 - 10 = 1 = (1/10) × 100 = 10 % So, radius will increase by 10 % Now, Volume Volume of Sphere = 4/3πr³ Ratio of volumes = 4/3πr³ : 4/3πR³ r³ : R³ (10)³ ...
Oct 17, 2024 · r is the radius of the sphere; V is the volume of the body; is the density of the body; Given: Radius of the sphere (r) = 6 cm; Density of the sphere = 0.010 g/cm³; Area of contact (A) = 0.0020 m² = (0.0020 × 10000) cm² = 20 cm².
