cm. Its total surface area is​

Answer 1

Its surface area would be 235.71 sq. cm.

Step-by-step explanation:

Since we have given that

base radius = 5 cm

Height = 10 cm

So, the surface area of circular cylinder would be

$\pi r$

$= \frac{22}{7} \times 5(5 + 10)$

$= \frac{22}{7} \times 5 \times 15$

$= 235.71$

Hence, its surface area would be 235.71 sq. cm.

Answer 2

Answer:

$\huge\mathfrak\orange{answer :-}$

Given,

The radius of a solid cylinder (r) = 5cm

Height (h) = 10cm

Hence,

Total surface area =

$2\pi \: rh + 2\pi \: {r}^{2}$

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

$= 2\pi \: \times 5(10 + 5)$

$= \pi \: \times 10 \times 15$

$= 150 {\pi}^{} {cm}^{2}$

Step-by-step explanation:
