Question

Can someone PLEASE HELP me with this??? i really don't know what to do

Answer 1

$\sf\purple{The\:radius\:of\:the\:cylinder\:is\:approximately \:28 \:ft.}$

Given:-

$\sf\blue{Height\:of\:the\:cylinder\:(h) }$ = 10 ft.

$\sf\pink{Volume\:of\:the\:cylinder}$ = 25,456 ft³.

To find:-

$\sf\purple{The\:radius\:of\:the\:cylinder.}$

Step-by-step explanation:-

We know that,

$\sf\red{Volume\:of\:a\:cylinder}$ =$\pi {r}^{2} h \\ ✒ \: 25456 \: {ft}^{3} = \pi {r}^{2} \times 10 \: ft \\ \: ✒ \: {r}^{2} = \frac{25456 \times 7 \: {ft}^{3} }{22 \times 10 \: ft} \\ ✒ \: {r}^{2} \: = \frac{178192 \: {ft}^{2} }{220} \\ \: ✒ \: {r}^{2} = 809.9636 \: {ft}^{2} \\ \: ✒\: r \: = \sqrt{809.9636 \: {ft}^{2} } \\ ✒ \: r \: = 28.45 \: ft$

Hence, the radius of the cylinder is 28.45 feet.
