Question

What is the surface area of a cylinder with the given dimensions? express your answer to nearest hundredth. use 3.14 for pi. radius = 5 cm.; height = 8 cm.

a. 582.45 sq. cm
c. 408.20 sq.cm
b. 281.34 sq.cm
d. 347.80 sq. cm?

Answer 1

The surface area of a cylinder is calculated through the equation,
SA = 2πr (h + r)
where r is the radius and h is height.

Substituting the known values to the equation above,
SA = 2π(5 cm)(8 cm + 5 cm)
SA = 408.20 sq.cm

Therefore, the answer is C. (based on your choices)
