Explanation:

Given:

Curved surface of cylindrical can = 162
\pi

Height of cylindrical can = 9 Cm

Find:

Diameter of the can = ?

Computation:

Curved surface of cylindrical can = 2
\pirh


162\pi = 2\pi rh\\\\(162\pi )/(2\pi )= r* 9\\\\81 = r* 9\\\\(81)/(9)=r


r=9 Cm

Diameter of the can = 2×r

Diameter of the can = 2×9 Cm

Diameter of the can = 18 Cm
