Answer: 21 inches

The diameter is 42, so you cut this in half to get 21. The height of 36 does not affect the diameter or radius, so we can ignore it.

Angles U and V are supplementary angles. The ratio of their measures is 7:13 Find the measure of each angle

GREYUIT [131]

If $u$ and $v$ are <span>supplementary angles, then

$u+v=180^{\circ}~~~~~\mathbf{(i)}$

The ratio of $u$ and $v$ is $\dfrac{7}{13}:$ <span>

$\dfrac{u}{v}=\dfrac{7}{13}\\\\\\ u=\dfrac{7v}{13}~~~~\mathbf{(ii)}$

Substitute $\mathbf{(ii)}$ into $\mathbf{(i)}:$

$\dfrac{7v}{13}+v=180^{\circ}\\\\\\ \left(\dfrac{7}{13}+1 \right )\cdot v=180^{\circ}\\\\\\ \left(\dfrac{7}{13}+\dfrac{13}{13} \right )\cdot v=180^{\circ}\\\\\\ \dfrac{20}{13}\cdot v=180^{\circ}\\\\\\ v=180^{\circ}\cdot \dfrac{13}{20}\\\\\\ \boxed{\begin{array}{c} v=117^{\circ} \end{array}}$

From $\mathbf{(i)},$ we find the measure of $u:$

$u=180^{\circ}-v\\\\ u=180^{\circ}-117^{\circ}\\\\ \boxed{\begin{array}{c} u=63^{\circ} \end{array}}$

Which inequality is true?

DiKsa [7]

Answer:

C. 5 $\pi$ > 15

Step-by-step explanation:

In the given series of inequalities, the inequality sign determines the final outcome.

A. 4 $\pi$ - 2 < 10

4 $\pi$ < 12

$\pi$ < 3

Since $\pi$ < 3, then the inequality is false

B. $\pi$ + 9 < 12

$\pi$ < 3

Since $\pi$ < 3, then the inequality is false

c. 5 $\pi$ > 15

$\pi$ > 3

Since $\pi$ > 3, then the inequality is true

D. 6 > 2 $\pi$

3 > $\pi$

Since $\pi$ < 3, then the inequality is false

Thus, the only inequality that is true is option C.
