A rectangle represents a figure with four sides having equal opposite sides and the inside angle between the two adjacent sides is ninety degree.
When any plane is made to pass through the cylinder creating a cross section which is perpendicular to its base, it results a two-dimensional cross sectional shape of a rectangle.
So the formula for a volume of a sphere is 4/3 times pi times the radius cubed. step one: 4/3 times 3.14 = 4.18666666667 Step two: then you cube 8.5 and get 592.45 the final answer is 2,480.3906
