Find the surface area of a cylinder with a base radius of 2 cm and a height of 3 cm.
Use the value 3.14 for π, and do not do any rounding.
Be sure to include the correct unit.

62.8cm^2

Step-by-step explanation:

The surface area of a cylinder is calculated by 2πrh+2πr2

where π is a constant, given as 3.14; h is the height, given as 3cm and r is radius, given as 2cm.

Therefore, rh = 3 x 2= 6 cm ^2 while r^2 =2 × 2= 4 cm^2.

Slot the values into the formula:

V= 2 (3.14) x 6 + 2 (3.14) x 4

V=37.68 + 25.12

V=62.8cm ^2
