Question

The sphericity of a cylinder of 1 cm diameter and length 3 cm is​

Answer 1

Answer: 9.43$cm^{2}$

Step-by-step explanation:

• The sphericity of a cylinder means the curved surface area.
• Given, r=$\frac{1}{2}cm$=0.5cm and h=3cm
• Curved surface area=$2\pi rh$

                                          =$2*\frac{22}{7}*(0.5)*3$

                                          =9.428$cm^{2}$ or 9.43$cm^{2}$

• Hence,the sphericity of the cylinder is 9.43$cm^{2}$.
