Solve the formula V = pi r2h for r

Mathematics

Andrei [34K]2 years ago

Answer:

V=\pi \times r^{2}\times h\\\\\Longrightarrow V=r^{2}\times \left( \pi \times h\right)  \\\\\Longrightarrow r^{2}=\frac{V}{\pi \times h} \\\\\Longrightarrow r=\sqrt{\frac{V}{\pi \times h} }

Answer:

root(V / hpi) = r

Step-by-step explanation:

i assume this is the volume of a cylinder and as such
V = pi * r^2 * h
divide both sides by hpi
V / hpi = r^2
root both sides
root(V / hpi) = r

Answer:

x = 10

Step-by-step explanation:

Use Pythagorean theorem to find the value of x

Focus only on one half of the triangle

if we slice the triangle in half, we get a right angle triangle

the base will now be 12/2 = 6

Pythagorean theorem says that a^2 + b^2 = c^2

plug 6 as a and 8 as b.

this should give you 100

now take the square root to find c (which equals x)

Ta-da!
