Question

find the CSA of cylinder whose circumference is 44cm and height 10 cm​

Answer 1

cylinder...

H=10 cm

$2\pi \: r \: = 44 \\ 2 \times \frac{22}{7} \times r = 44 \\ r = \frac{44 \times 7}{2 \times 22} \\ r = 7 \: cm$

CSA=

$2\pi \: r \: h \: \\ 44 \times 10 \\ 440 \: \: {cm}^{2}$

Answer 2

Answer:

Curved Surface Surface Area of Cylinder = 440 cm²

Step-by-step explanation:

Given: Circumference of Base of Cylinder,  $2\pi r$ = 44 cm

           Height of Cylinder, h = 10 cm

To Find: Curved Surface Area of Cylinder

Curved Surface Area of Cylinder = $2\pi rh$

                                                       = $(2\pi r)\times h$

                                                      = Circumference of Circle × Height

                                                       = 44 × 10

                                                       = 440 cm²

Therefore, Curved Surface Surface Area of Cylinder = 440 cm²
