V=pir^2h solve this equation for h

Nady [450]

Since we are solving for h, the equation:

V = πr²h

...divides πr² to the other side. Thus, it becomes....

$\frac{V}{ \pi r^2}$ = h

Which can be rewritten as....

h = $\frac{V}{ \pi r^2}$

I need the answer please help!

Option C is the correct answer as SAS stands for Side, Angle, Side. You would need one side, one angle and another side to be the same for the conditions for congruency to be met.

The curve with equation y2 = x3 + 3x2 is called the tschirnhausen cubic. find an equation of the tangent line to this curve at t

MAVERICK [17]

First find the slope, take derivative of both sides with respect to x.
2y dy/dx=3x^2+6x
solve for dy/dx
dy/dx=[3x^2+6x]/2y
plug in given vales of (1,2(
dy/dx=9/4

now you have everything you need to plug into point slope form
y-2=(9/4)(x-1)
answer is y=(9/4)x+(1/4)
