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 301.6 units2
The curved surface area is 113.1 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 base areas quadruple and the curved surface doubles.
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.
