False.

Two figures may be different shape and have the same perimeter (a square and a circle, for example). If they are different shape, they will not be congruent.

Find the surface area of the cylinder

Alik [6]

Answer:

Surface Area = 282.6 cm²

Step-by-step explanation:

Formula: SA = 2 $\pi$ rh + 2 $\pi$ r²

SA = 2 $\pi$ rh + 2 $\pi$ r²

SA = 2(3.14)(5)(4) + 2(3.14)(5)

SA = 2(3.14)(5)(4) + 2(3.14)(25)

SA = 125.6 + 157

SA = 282.6 cm²
