Question

use the diagram shown below to answer the question below :
r= 5cm c = 32cm h= 14 cm

Find the area of one of the two circles for the cylinder above. Use 3 for an approximation of pi.
What is the surface area of the cylinder?​

Answer 1

Answer:

Definition: The number of square units it takes to exactly cover the surface of a cylinder. Given by the formula:

area = 2 π r 2 + 2 π r h

where:

π is Pi, approximately 3.142

r is the radius of the cylinder

h height of the cylinder
