A square with an area of 49 cm2 is rotated to form a cylinder. What is the volume of the cylinder?

A square has an area of 49 cm²A = a²a = √49 = 7 cmIf the square is rotated to form a cylinder than:r = 7 cm (radius of the base), h = 7 cm (height of a cylinder). V = r² π hV = 7² π · 7Answer:

V = 343 π cm³ ≈ 1,077.02 cm³
