Answer 1

Answer:

3960

Step-by-step explanation:

dimensions of net is 88 and 45cm

it is rolled along it's legth to form a cylinder

hence,it's width will be the circumference of the cylinder

2πr=45 and h=88cm

curved surface area of cylinder = 2πrh= 45*88

= 88*45

=3960cm2

A rectangular mosquito net having dimensions 88 cm 45cm is rolled along its length to form a cylinder Find the curved surface area of the cylinder?

$\huge\mathcal{\fcolorbox{cyan}{black}{\blue{➥Aภรฬҽɾ࿐}}}$

GIVEN -

➙Length = 88cm

➙Breadth = 45cm

TO FIND -

➙Curved Surface Area Of Cylinder = ?

FORMULA USED -

➙Circumference of Circle = $2 \: \pi \: r$

➙Curved Surface Area Of Cylinder = $2 \: \pi \: r \: h$

SOLUTION -

➣If the sheet is rolled along its length then the circumference will be equal to the length of the rectangle.

➣Circumference of Circle = 88cm

➙r = 88 × 7 /22 × 1/2

➙r = 14 cm

➣Also, height of the cylinder will be equal to the breadth of the rectangle.

➙h = 45 cm

➢Therefore,

➣Curved Surface Area Of Cylinder = 2 × 22/7 × 45 × 14

= 3960 cm²
