radius = 2 i believe they mean forming a sphere, if you can imagine a 2d circle with a radius of 2 being "circled" about (for lack of a better word) around a 3d axis to create a sphere. the volume of a sphere is 4/3pi*r^3, which would make the volume of this sphere (32/3)pi

Volume = (1/2) *1/3 (3.14) (R)^2 (H) V = (1/2) 1/3 (3.14)(1)^2 (4) V = 4pi/6 2 pi/3
