Question

Radius of cyclinder 1.4 and length 5.2 . Calculate surface area of cylinder

Answer 1

Answer:

The surface area of a cylinder is 58.0272.

Step-by-step explanation:

Surface area = 2×\pi × r × r + 2×\pi × r × h

2 × 3.14 × 1.4 × 1.4 + 2 × 3.14 × 1.4 × 5.2

12.3088 + 45.7184

58.0272 is the surface area of a cylinder.

Answer 2

Given that,

Radius of cylinder is 1.4

Height of cylinder is 5.2

To find

The surface area of cylinder

Solution,

The surface area of a cylinder is given by :

$S=2\pi r(r+h)$

Plugging the values in the above equation such that,

$S=2\times \dfrac{22}{7} \times 1.4\times (1.4+5.2)\\\\S=58.08\ \text{unit}^2$

So, the surface area of cylinder is $58.08\ \text{unit}^2$.
