Question

Calculate the curved surface area of a cylindrical drum whose dimensions are diameter 5cm, height 30cm​

Answer 1

Answer:

150$cm^{2}$

Step-by-step explanation:

Curved surface area of a cylinder = 2$\pi rh$

Radius=$\frac{5}{2}$cm

Height=$30$cm

Curved surface area of a cylinder=$2\pi rh$

                                                        = 2 x $\frac{5}{2}$ x 30

                                                       = 150 $cm^{2}$
