1. ★ Given :

   • Diameter = 14 cm

   • Radius = 7cm

   • Height = 6cm

   ★ To find :

   • CSA of cylinder

   • TSA of cylinder

   • Volume of cylinder

   ★ Solution :

   • First, By using the formula of Curved Surface Of Cylinder, Where π is 22/7, R is radius and H is Height.

   • Then with the formula of Total surface area of cylinder We will get the TSA of cylinder.

   • At last with the formula of Volume Of Cylinder, we will find the volume.

   ✰ CSA of cylinder = 2πrh

   ✰ TSA of cylinder = 2πr (h + r)

   ✰ Volume of cylinder = πr²h

   Let’s Find out…!

   CSA of cylinder = 2πrh

   ➤ 2 × 22/7 × 7 × 6

   ➤ 44 × 6

   ➤ 264 cm²

   ___________

   TSA of cylinder = 2πr (h + r)

   ➤ 2 × 22/7 × 7 (7 + 6)

   ➤ 44 (7 + 6)

   ➤ 44 × 13

   ➤ 572 cm²

   ___________

   Volume of cylinder = πr²h

   ➤ 22/7 × 7 × 7 × 6

   ➤ 154 × 6

   ➤ 924 cm²

   ___________

   Therefore,

   i.) CSA of cylinder = 264 cm²

   ii.) TSA of cylinder = 572 cm²

   iii.) Volume of cylinder = 924 cm²

   ___________

2. Answer:

   Volume of cylinder of radius r and height h is given by =πr²h as radius = 2/Diameter = 14/2 =7cm

   ⇒ Volume = 22/7 x 7² x 6=

   = 924cm³
