Answer:

As = 2112 cm²

Step-by-step explanation:

given:

A cylinder has a circular base radius 14cm and height of 10cm.

find:

the total surface area of the cylinder. [take pie 22/7] *​

solution:

<u>surface area (As) = 2πrh + 2πr²</u>

where r = 14 cm;    h = 10 cm;   π = 22/7

plugin values into the formula:

As = 2 (22/7) 14 (10) + 2 (22/7) 14²

As = 880 + 1232

As = 2112 cm²
