Question

the area of the curved surface of a cylinder is 4400 CM square and the circumference of its base is 110 CM find the height of the cylinder​

Answer 1

Step-by-step explanation:

Circumference of its base =110cm

2πr=110

2× 7/22 ×r=110

7/44 ×r=110

r=17.5cm

Curved Surface Area =4400cm²

2πrh=4400

2× 7/22 ×h×17.5=4400

7/44 ×17.5×h=440

h= 4400/40 ×2.5

h=40cm

Volume = πr² h

= 7/22 ×17.5×17.5×40

=38500cm²
