Marcia claims that the GCF for (2x2 + 4xy + 8xy4) is 8x2y4.
miskamm [114]
She is not correct.
The GCF for 2x^2 + 4xy + 8xy^4
is 2x
The first term does not have a 'y' in it so you cannot have a 'y' in the GCF.
The second and third terms both only have 1 'x', so you can only take out 1 'x', not 2.
The highest constant that all three terms have in common is a 2.

What is the volume of a sphere with a radius of 3 m, rounded to the nearest tenth
expeople1 [14]
<h3><u>Given</u>:-</h3>

\rightarrowRadius(r) of sphere = 3m

<h3><u>To Find</u>:-</h3>

\rightarrow Volume of the sphere.

<h3><u>Formula Used</u>:-</h3>

\rightarrowVolume of sphere = \sf{\frac{4}{3}πr^3}

<h3><u>Solution</u>:-</h3>

\rightarrowVolume of sphere = \sf{\frac{4}{3}πr^3}(putting the value of r(radius) from the above given and pie(π) = \sf{\frac{22}{7}})

\rightarrow\sf{=\frac{4}{3}×\frac{22}{7}×3^3}

\rightarrow\sf{=\frac{4}{3}×\frac{22}{7}×27}

\rightarrow\sf{=\frac{2,376}{21}}

\rightarrow\sf{=113.14m^3}

Therefore, the volume of the sphere \sf{=113.14m^3}, which can be rounded off to it's nearest tenth as \sf{113.1m^3}
