Question

What is the surface area of the cylinder with height 4 m and radius 2 m? Round your answer to the nearest thousandth. ​

Answer 1

Answer:

         75.398 m²

Step-by-step explanation:

$A=2\cdot\pi R^2+ 2\pi R\cdot H\\\\H=4\,m\\R=2\,m\\\\A=2\cdot\pi\cdot 2^2+2\pi \cdot2\cdot4=8\pi+16\pi=24\pi=75.398223....\approx75.398\ m^2$
