Question

the curved surface area of a right circular cylinder is 4400 CM square if the circumference of the base is 110 cm find the height of the cylinder

Answer 1

given,

CSA of the cylinder= 4400 square cm

circumference = 110 cm

To find,
height of the cylinder

soln:
circumference = 110
=> 2πr =110
=> r = 110*7/2*22
=> r = 35/2
therefore, radius is 35/2 or 17.5

now,

CSA of the cylinder = 4400

=> 2πrh = 4400

=> 2 * 22/7 * 35/2 * h = 4400

=> h = 4400 * 7 * 2 / 2 * 22 *35

=> h = 40 cm

Therefore, the height of the cylinder is 40 cm

thank you☺☺
