BRAINLIST PLEASEEEE HELP

Answer 1

Answer:

About 527.79

Step-by-step explanation:

formula is A=2πrh+2πr^2

Answer 2

Answer:

$527.52\:\mathrm{in^2}$

Step-by-step explanation:

The surface area of this cylinder consist of two circles and a 3D outer edge with respect to the circumference. The area of a circle is given as $r^2\pi$. Using $\pi=3.14$ as requested in the problem, the area of both these circles is:

$2\cdot6^2\cdot 3.14=226.08\:\mathrm{in^2}$.

The area of the outer edge is the circumference of the circle multiplied by the height. The circumference of a circle is given by $2r\pi$.

Therefore, the circumference's 3D outer edge is:

$8\cdot2\cdot6\cdot 3.14 = 301.44\:\mathrm{in^2}$.

Adding these up, the total surface area is:

$226.08+301.44=\fbox{ 527.52\:\mathrm{in^2} }$.
