Question

Me ayudan despejando r,
V=1/3 *pi*h(r²+R²+rR)

Answer 1

Explicación paso a paso:

V  = 1/3 × π × h(r² + R² + rR)

V = 1/3 × π × h(r² + R² + rR)

3v = π × h(r² + R² + rR)

(3v/πh) = r² + R² + rR

3v/πh - R² + rR = r²

[3v - πh(R² +rR)]/πh = r²

[3v - πhR² + πrR]/πh = r²

$\boxed{\sqrt{\dfrac{3v - \pi\ hR^{2} + \pi\ rR}{\pi\ h}  } =r }$
