The volume of a right circular cone is found using the equation V = 1 3 π r 2 h . Which equation represents the volume solved fo

alex41 [277]

Solving for a variable in an equation means, we are changing the subject of formula of the equation.

The equation of r is: $\mathbf{r = \sqrt{\frac{3V}{\pi h}}}$

The equation is given as:

$\mathbf{V = \frac 13 \pi r^2h}$

We start by multiplying both sides by 3

$\mathbf{V \times 3= \frac 13 \pi r^2h \times 3}$

Rewrite as:

$\mathbf{3V= \pi r^2h}$

Divide both sides by $\mathbf{\pi h}$

$\mathbf{\frac{3V}{\pi h}= \frac{\pi r^2h}{\pi h}}$

Cancel out common factors

$\mathbf{\frac{3V}{\pi h}= r^2}$

Take square roots of both sides

$\mathbf{\sqrt{\frac{3V}{\pi h}}= \sqrt{r^2}}$

Evaluate the right-hand sides

$\mathbf{\sqrt{\frac{3V}{\pi h}}= r}$

Make r the subject

$\mathbf{r = \sqrt{\frac{3V}{\pi h}}}$

Hence, the resulting equating for r is:

$\mathbf{r = \sqrt{\frac{3V}{\pi h}}}$

Find x. A. 11√6/2 B. 22 C. 33 D. 11√3/2

Phoenix [80]

Answer:

Step-by-step explanation:

using the tangent ratio on the triangle on the right and the exact value

tan60° = $\sqrt{3}$ , then letting the altitude be h

tan60° = $\frac{opposite}{adjacent}$ = $\frac{11\sqrt{6} }{h}$ = $\sqrt{3}$ ( multiply both sides by h )

11 $\sqrt{6}$ = h × $\sqrt{3}$ ( divide both sides by $\sqrt{3}$ )

11 $\sqrt{2}$ = h

using the sine ratio in the triangle on the left and the exact value

sin45° = $\frac{\sqrt{2} }{2}$ , then

sin45° = $\frac{opposite}{hypotenuse}$ = $\frac{h}{x}$ = $\frac{11\sqrt{2} }{x}$ = $\frac{\sqrt{2} }{2}$ ( cross- multiply )

$\sqrt{2}$ × x = 22 $\sqrt{2}$ ( divide both sides by $\sqrt{2}$ )

x = 22
