Hi! how do i find surface area of a cylinder? for some reason i can’t get the right answer
asambeis [7]
SA=2\pi r^2+2\pi rh

Use the formula above to find the surface area of a cylinder.

For the given cylinder the given data is the height (6mi) and diameter (16mi), use the diameter to find the radius:

\begin{gathered} r=\frac{d}{2} \\  \\ r=\frac{16mi}{2}=8mi \end{gathered}

Surface area:

\begin{gathered} SA=2\pi(8mi)\placeholder{⬚}^2+2\pi(8mi)(6mi) \\ SA=128\pi mi^2+96\pi mi^2 \\ SA=224\pi mi^2 \end{gathered}Then, the surface area of the given cylinder is: 224π square miles

Naya [18.7K]
We know that

1 ft-----------> 0.3048 m
then
1 ft²---------> (0.3048)²------> 0.092903 m²
so
121 ft²----------> 121*0.092903----------> 11.24 m²

the answer is
11.24 m²
