OpenStudy (vickyisthesmartone123):

OpenStudy (vickyisthesmartone123):

OpenStudy (anonymous):

There are two semi-circles and 1 rectangle.

OpenStudy (anonymous):

Rectangle: \(\sf A = lw\) Plug in what we know: \(\sf A = (18)(8)\) Multiply

OpenStudy (vickyisthesmartone123):

yea so can you solve it for me please? I know the answer to multiplying is 144

OpenStudy (anonymous):

Circle: Two semi-circles = 1 circle \(\sf A = \pi r^2\) Plug in wht awe know: \(\sf A = (3.14)(4^2)\) Simplify

OpenStudy (anonymous):

Yes, now we find the volume to this^ and add it to 144.

OpenStudy (vickyisthesmartone123):

50.24

OpenStudy (anonymous):

Yes, now add 144 + 50.24

OpenStudy (vickyisthesmartone123):

194.24

OpenStudy (anonymous):

Yes, so our answer is approximately 194.2 square feet.
