Question

find the curved surface of cylindar of height 28cm is 352sq.cm.find the diameter of the base of the cylindar

Answer 1

Hey mate______

Here is your answer-
_______

let,
Height of cylinder ( h ) = 28cm
Curved surface area of cylinder = 352sq.cm
Radius of cylinder = ?

Curved surface area of cylinder = 2πrh

352 = 2 × 22/7 × r × 28

r = 352 × 7/ 2 × 22 × 28

r = 16 / 4 × 2

r = 16/8

r = 2cm

Diameter of base of cylinder = 2r

= 2 × 2

= 4cm

Therefore, the diameter of a cylinder is 4cm

QUESTION➡


Find the curved surface of cylinder of height 28cm is 352 square cm. Find the diameter of the base of the cylinder.



SOLUTION➡


Curved Surface Area of Cylinder= 352 cm^ 2

Height = 28 cm

Radius = ?



______________________________________

Curved Surface Area of Cylinder= 2πrh


$= > 352 = 2 \times \frac{22}{7} \times r \times \times 28$


$= > 352 = 2 \times 22 \times r \times 4$



$= > r = \frac{352}{2 \times 22 \times 4}$



$= > r = 2 \: \: cm$



_______________________________________


$d = 2 \times r$




$= > d = 2 \times 2$




$= > d = 4 \: \: cm$


Therefore,


Diameter = 4 cm
