Answer:

x = 5.1

Step-by-step explanation.

Our first step is to find all the angles. If b = 91 degree and c is 38, a. has to be 51 because all triangles add up to 180 degree. Because we have both B and b, we can use sine law.

a/A 13/sin91 c/38

we can use b in this situation.

The legnth of a is 10.1.

So, x-5 would be 5.1

Answer:

r = √(3V/(πh))
r ≈ 1.78 cm

Step-by-step explanation:

Multiply by the inverse of the coefficient of r², then take the square root.

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

For V=50, h=15, this is ...

${r=\sqrt{\dfrac{3(50)}{\pi(15)}}=\sqrt{\dfrac{10}{\pi}}\approx\boxed{1.78\quad\text{cm}}$
