Question

A closed metal cylindrical container has a base radius of 5 cm and height of 12find the total surface area of container.....


Vaibhav aap kisi rupanshee ko janta ho kya plz batao na......​

Answer 1

Step-by-step explanation:

Volume of cylinder is given by π*r^2*h, where r is the radius and h is the height. so if Radius is doubled and height is halved then new volume will be twice the initial volume.

Answer 2

Answer:

The total surface area of container is 534.14 sq cm.

Step-by-step explanation:

We know,

Total surface area = 2πr(r+h) sq units

Here, radius(r) = 5cm and height(h) = 12cm

Therefore,

2πr(r+h)

= 2×22/7×5(5+12)

= 220/7(17)

= 31.42×17

= 534.14(Answer)

Hope it helps you.
