Surface Area and Volume of Cone and Cylinder

The height of a cylinder is 5 cm and the diameter of the base is 14 cm.
What is the total surface area of the cylinder? [ Assume π =

22 / 7

]

Please fill out the fields marked in red.

Explanation

Well done !

Explanation:

We are given that:
Height of cylinder (h) = 5 cm,br> Base radius of cylinder(r) =

14 / 2

= 7 cm
Total Surface area of cylinder = 2πr (r + h)
Substituting the values of r and h, we get
Total Surface area of cylinder = 2 ×

22 / 7

× 7(7 + 5)
= 2 × 22 × 12 = 528
Therefore, total surface area of the cylinder is 528 cm².

Explanation

Wrong answer !

528 cm²

Explanation :

We are given that:
Height of cylinder (h) = 5 cm,br> Base radius of cylinder(r) =

14 / 2

= 7 cm
Total Surface area of cylinder = 2πr (r + h)
Substituting the values of r and h, we get
Total Surface area of cylinder = 2 ×

22 / 7

× 7(7 + 5)
= 2 × 22 × 12 = 528
Therefore, total surface area of the cylinder is 528 cm².
