WebThe volume of a sphere with radius a may be found by evaluating the triple integral V = ∭ S dxdydz, where S is the volume enclosed by the sphere x2 + y2 + z2 = a2. Changing variables to spherical polar coordinates, we obtain V = 2π ∫ 0dϕπ ∫ 0dθa ∫ 0r2sinθdr = 2π ∫ 0dϕπ ∫ 0sinθdθa ∫ 0r2dr = 4πa3 3, as expected. Share. WebJun 11, 2009 · See answer (1) Copy. Technically, a circle is a 2-dimensional object, so the question should read "volume of a sphere " OR " Area of a circle". The formula to work out the volume of a sphere is: 4/3 pi x r3, where "r" is the radius of the sphere. To find the area of a circle: pi x r2.
