Question

Which of the following equations is equivalent to s=πr^2h

Answer 1

Answer:

The equation $h=\frac{s}{\pi r^2}$ is equivalent to $s=\pi r^2h$. The correct option is B.

Step-by-step explanation:

The given equation is

$s=\pi r^2h$

Divide both sides by $\pi r^2$ to isolate h.

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

Cancel out common factors.

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

Therefore the equation $h=\frac{s}{\pi r^2}$ is equivalent to $s=\pi r^2h$. The correct option is B.

Answer 2

Answer:

h = s / π.r²

Step-by-step explanation:

the given equation is s = π.r².h

Now if we have to calculate the value of h from the given formula then we will solve it so that h remains alone on one side of the equation.

This only possible when we divide term on both the sides by π.r²

s/π.r² = π.r².h/π.r²

h = s / π.r²

Therefore h = s / π.r² is the right option.
