Question

3 For a right circular circular cylinder.if.base radius.is.14cm.and.height.is.10cm.then.find.its.curved.surface.area.and.total.surface.area​

Answer 1

Curved surface area of cylinder =2πrh

Given, r=14 cm, π= 22/7 and h=10 cm

Curved surface area of cylinder

=2×22/7×14×10

=44×2×10=880 cm2 .

Answer 2

Step-by-step explanation:

Curved Surface Area = $2\pi rh$

                                     =$2 * \frac{22}{7} * 14 cm * 10 cm$

                                      = 880 cm2

Total Surface Area = $2\pi rh$ $+ 2\pi r^2$

                                     =$2 * \frac{22}{7} * 14 cm * 10 cm$ $+ 2 * \frac{22}{7} * 14 cm *14 cm$

                                      = 2112 cm2
