Find the value of “X”

marta [7]

Answer:

x = 55

Step-by-step explanation:

A triangle equals 180 degrees, b will be used to find the missing angle.

21 + 34 + b = 180

55 + b = 180

subtract 55 from both sides

b = 125

A straight line is 180 degrees and the b, the missing angle, and x are supplementary angles so

125 + x = 180

x = 55

Rewrite the formula to solve for the positive value of r in terms of h and v.

Zigmanuir [339]

Answer:

$r=\sqrt{\dfrac{3V}{\pi h}}$

Step-by-step explanation:

The formula for the volume of a cone is given by :

$V=\dfrac{1}{3}\pi r^2 h$

Where

r is radius of cone and h is its height

We need to solve the above formula for r.

Cross multiplying both sides of the given formula

$3V=\pi r^ 2h$

Dividing both sides by πh.

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

So, the formula for r is $\sqrt{\dfrac{3V}{\pi h}}$
