Answer 1

Answer:

ok I will hope it help u hehe

Answer 2

Answer:

314.28 cm²

Step-by-step explanation:

Height = 10 cm  

Radius = 5 cm

To calculate the surface area of a cylinder, you need to find the Base Area (B) and Curved Surface Area (CSA). Therefore, the surface area or the total surface of a cylinder is equal to the sum of the base area times two and the area of the curved surface.

$Curved Surface Area _{(cylinder)} = 2\pi rh$  

The value of π = $\frac{22}{7}$  

2 × $\frac{22}{7}$ × 5 × 10

= 2 × 22 × 5 × 10 × $\frac{1}{7}$

=  2200 × $\frac{1}{7}$

= $\frac{2200}{7}$

= 314.28 cm²
