Question

Find the total surface area of a cylinder whose diameter is 28 cm and height is 26 cm
​

Answer 1

Answer:

$2376 {cm}^{2}$

Formula of Total surface area of cylinder

$2\pi \times r \times h + 2\pi {r}^{2}$

Height is 26cm

Diameter is given 28 cm

The formula is for radius

So radius =d/2

= 28/2

= 14cm

I have solved in attachment

Answer 2

Step-by-step explanation:

given

diameter of cylinder = 28cm

height of cylinder = 26cm

radius is half of diameter = 28/2

so radius = 14cm

total surface area of cylinder = 2 ×22/7 ×14×26

=2778

so total surface area of cylinder is 2778
