Question

what is the TSA of cylinder whose radius is 33 cm and height is 56 cm

Answer 1

Answer:

Tsa of cylinder =2pir r(r+h)

2×22/7×33(33+56)

44/7×33(89)

6.285×33(89)

207.43(89)

18461.14

Answer 2

Answer :-

• TSA of cylinder = 18461.14 cm² [Approx.]

Given :-

• Radius of cylinder = 33 cm
• Height of cylinder = 56 cm

To Find :-

• TSA of cylinder = ?

Explanation :-

As we know, TSA of cylinder means the total area of material to required to make it with it's base and top.

$\green { \boxed { \bf \bigstar \; TSA \; of \; cylinder = 2 \pi r \; (r+h) \; \bigstar }}$

$\rm : \; \longmapsto 2 \times \dfrac{22}{7} \times 33 \; (33+56) \; \; cm^2$

$\rm : \; \longmapsto \dfrac{44}{7} \times 33 \; (89) \; \; cm^2$

$\rm : \; \longmapsto \dfrac{1452}{7} \times 89 \; \; cm^2$

$\rm : \; \longmapsto \dfrac{129228}{7} \; \; cm^2$

$\purple { \underline { \boxed { \bf : \; \longmapsto 18461.14 \; \; cm^2 \qquad [Approx.] }}}$

Hence, the TSA of cylinder is 18461.14 cm² [Approx.]
