The formula to calculate the volume of a sphere is V = (4/3)πr^3, where r is the radius of the sphere. Given a radius of 3.1, we substitute this value into the formula: V = (4/3)π(3.1)^3. Calculating this gives us V ≈ 127.6 cubic units.
The formula for calculating the volume of a hexagonal prism is to take the area of the hexagon, then multiply it by the height of the prism.
The volume of a sphere is given by the formula V =⁴⁄ ₃πr3The volume of a sphere with radius 7cm = ⁴⁄ ₃π73 = 1436.76 cm3 (to 2 dps)
the formula for the volume of a cuboid is length x breadth x height
