Entire surface area = (2piradius2)+(pidiameterheight) in square units
area of base x height
The curved surface area of this cylinder is 251.33 units2
the circumfrance of the base x the height of the cylinder
The curved surface area is 301.6 units2
The curved surface area is 201.06 units2
area of base x height
The curved surface area of this cylinder is 251.33 units2
the circumfrance of the base x the height of the cylinder
The curved surface area is 113.1 units2
The curved surface area is 301.6 units2
The curved surface area is 201.06 units2
Total surface area = 2*pi*r*(r + h) where r is the base radius and h the height.
The surface area of the 'wall' doubles, but the base areas remain the same.
188.4 cm2
The surface area of the base = Pi x r2 = Pi x 9 cm2 But to calculate the surface area of a cylinder you also need to know its height. The cylindrical surface area will be Pi x 2r x height = (in this case) Pi x 6 x height.
The base areas quadruple and the curved surface doubles.
