The formula of a volume of a rectangular prism: V = lwh
l - length
w - width
h - height
We have the volume:
![V=6x^3-x^2-2x=x(6x^2-x-2)=x(6x^2+3x-4x-2)\\\\=x[3x(2x+1)-2(2x+1)]=x(2x+1)(3x-2)\\\\Answer:\ \boxed{A.\ Height:3x-2,\ Length:2x+1,\ Width:x}](https://tex.z-dn.net/?f=V%3D6x%5E3-x%5E2-2x%3Dx%286x%5E2-x-2%29%3Dx%286x%5E2%2B3x-4x-2%29%5C%5C%5C%5C%3Dx%5B3x%282x%2B1%29-2%282x%2B1%29%5D%3Dx%282x%2B1%29%283x-2%29%5C%5C%5C%5CAnswer%3A%5C%20%5Cboxed%7BA.%5C%20Height%3A3x-2%2C%5C%20Length%3A2x%2B1%2C%5C%20Width%3Ax%7D)
Answer: I would go with C I hope i am right!!
Step-by-step explanation:
<u>Part 1)</u> A 20° sector in a circle has an area of 21.5π yd².
What is the area of the circle?
we know that
the area of a circle represent a sector of
degrees
so by proportion
therefore
<u>the answer part 1) is</u>
The area of the circle is 
<u>Part 2)</u> What is the area of a sector with a central angle of 3π/5 radians and a diameter of 21.2 cm?
we know that
the area of the circle is equal to

where
r is the radius of the circle
in this problem we have

<u>Find the area of the circle</u>



<u>Find the area of the sector</u>
we know that the area of the circle represent a sector of
radians
by proportion
therefore
<u>the answer part 2) is</u>
the area of the sector is
