Question

PLS HELP!! I NEED TO FIND THE SURFACE AREA OF THIS CYLINDER!!!!!

Answer 1

Answer:

Step-by-step explanation:

you have two disks, and one rectangle

area of the disk = π $r^{2}$

47 π x 2 = 94 π (for the two disks....

rectangle area = L x W

width = 14

Length = 2*π*r = 14π

area = 14*14π = 196 π

total = 196 π + 94 π = 290 π

Answer 2

Answer:

The surface area of this cylinder is about 923.63 $inches^{2}$.

Step-by-step explanation:

The formula for the surface area of a cylinder is this :

$A = 2\pi rh+2\pi r^{2}$

"R" is 7, and "h" is 14. Knowing these values, let's solve.

$A = 2\pi rh+2\pi r^{2}$ = 2 · π · 7 · 14 + 2 · π ·72 ≈ 923.62824

The surface area of this cylinder is about 923.63 $inches^{2}$.

Hope this helps, please mark brainliest! :)
