Work out the surface area of this cylinder
8.2 cm
17.5 cm

1324.12 sq. cm.

Step-by-step explanation:

A=2πrh+2πr2

A = 2π x 8.2 x 17.5 + 2π x 8.2^2

A = 2π x 143.50 + 2π x 67.24

A= 1324.12

SA = 1324.1 cm²

Step-by-step explanation:

Surface Area of Cylinder =

Where r = 8.2 cm, h = 17.5 cm

=> SA =

=> SA =

=> SA = 901.6 + 422.5

=> SA = 1324.1 cm²

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
