Question

the radius and height of cylinder is 7cm and 14 cm then TSA is
​

Answer 1

Answer:

924 $cm^{2}$

Step-by-step explanation:

Given :

• Radius  of cylinder = 7cm
• Height of cylinder = 14 cm

To Find :

Total Surface Area of Cylinder = ?

Formula:

TSA = CSA + 2 × Base Area

⇒TSA = 2$\pi$rh  + 2 ×

          = 2$\pi$r(h + r)

Solution :

TSA = 2$\pi$r(h + r)

       = 2 × $\frac{22}{7}$ × 7 ( 14 + 7 )

       = 2 × 22 × 21

       = $\boxed {924 cm^{2} }$

Answer 2

Given:

The radius (r) of the cylinder is 7 cm

The height (h) of the cylinder is 14 cm

To find:

The Total Surface Area (TSA) of the cylinder

The formula to find the Total Surface Area of a cylinder is

TSA = 2πr(r + h) units sq.

TSA of cylinder

= 2 * 22/7 * 7 * (7 + 14)

= 2 * 22 * (21)

= 44 * 21

= 924 cm sq.

Hence

• The Total Surface Area (TSA) of the cylinder is 924 cm sq.

More information

• The Curved Surface Area (CSA) of the cylinder is 2πrh units sq.
• The volume of the cylinder is πr²h units cube.
