WebA sphere (from Greek σφαίρα — sphaira, "globe, ball,") is perfectly round geometrical object in three-dimensional space, such as the shape of a round ball. Like a circle in two … WebThe radius of the outer sphere is greater than that of the inner sphere. The volume of a hollow sphere can be calculated by subtracting the volume of the inner sphere from the volume of the outer sphere. Mathematically, The volume of a hollow sphere, \( V=\frac{4}{3}\times \pi \times (R-r)^3 \) cubic units Where, WebThe sphere is defined as the three-dimensional round solid figure in which every point on its surface is equidistant from its centre. The fixed distance is called the radius of the sphere and the fixed point is called the centre of the sphere. When the circle is rotated, we will observe the change of shape. scary ps4 games
