Work out the surface area and give your answer in terms of pi. Not sure of the steps, assistance appreciated.

138π m²

Step-by-step explanation:

The following data were obtained from the question:

Diameter (d) = 6 m

Height (h) = 20 m

Surface Area (SA) =?

Next, we shall determine the radius. This can be obtained as follow:

Diameter (d) = 6 m

Radius (r) =?

r = d/2

r = 6/2

r = 3 m

Finally, we shall determine the surface area of the cylinder. This can be obtained as follow:

Radius (r) = 3 m

Height (h) = 20 m

Surface Area (SA) =?

SA = 2πrh + 2πr²

SA = 2πr (h + r)

SA = 2 × π × 3 (20 + 3)

SA = 2 × π × 3 × 23

SA = 138π m²

Thus, the surface area is 138π m².

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
