Isabella uses the equation V = one-third (12) squared (9) pi to find the volume of the cone below.
lyudmila [28]

Isabella’s error is  Isabella should have divided the product of 12π and 9 by 3 to get V = 12π(9)/3 option fourth is correct.

<h3>What is a cone?</h3>

It is defined as a three-dimensional shape in which the base is a circular shape and the diameter of the circle decreases as we move from the circular base to the vertex.

\rm  V=\pi r^2\dfrac{h}{3}

Isabella equation:

\rm V = \dfrac{1}{3}(12)^2(9)\pi

The area of the base = 12π square cm

\rm V = \dfrac{12\pi (9 )}{3}

Thus, Isabella’s error is  Isabella should have divided the product of 12π and 9 by 3 to get V = 12π(9)/3 option fourth is correct.

The line represented by the equation 3x + 5y = 2 has a slope of -3/5 . Which shows the graph of this equation?
erica [24]
What exactly is being asked? the slope is easy as all you have to do is move the 3x over so that 5y = -3x + 2 
divide by 5 and you get y = -3/5x +0.4
that's the equation of the graph if that's what is being asked
