Answer:

3 cm

Step-by-step explanation:

First, find the volume of the cone.

V = $\frac{1}{3}$ $\pi$ r²h

V = $\frac{1}{3}$ (3.14)(9)(12)

V = 113.04

This means the sphere is also 113.04

Use the formula V = $\frac{4}{3}$ $\pi$ r³

113.04 = $\frac{4}{3}$ (3.14)r³

113.04 = 4.19r³

26.98 = r³

3 ≈ r

Four resistors are connected in series such that their total resistance is 50ohm . If the resistance of resistors is 5 ohm , 10o

Katyanochek1 [597]

<h2>Answer:</h2>

$\boxed{R_{4}=20\Omega}$

<h2>Step-by-step explanation:</h2>

If resistors are in series, so the current $I$ is the same in all of them. In this problem we have four resistors. So, we can get a relationship between the Equivalent resistance of series combination and the four resistors as follows:

$R_{eq}=R_{1}+R_{2}+R_{3}+R_{4}$

$R_{eq}$ is the total resistance $50\Omega$ . Moreover:

$R_{1}=5\Omega \\ R_{2}=10\Omega \\ R_{3}=15\Omega$

Therefore:

$50=5+10+15+R_{4} \\ \\ R_{4}=50-(5+10+15) \\ \\ R_{4}=50-30 \\ \\ \boxed{R_{4}=20\Omega}$
