Sphere B is the image of sphere A after dilation by a scale factor of 44. If the surface area of sphere B is 432 km^2, find the

Sergeeva-Olga [200]

<h2>Answer:</h2>

27 km²

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

$SA=4\pi Jr^2$

$4\pi r^2_B=432$

$r^2_B=\frac{108}{\pi}$

$r_B=\frac{6\sqrt3}{\sqrt{50}}$

$r_A=\frac{r_B}{4}=\frac{3\sqrt3}{2\sqrt\pi}$

$S_0SA=4\pi Y\begin{matrix}2\\A\\\end{matrix}$

$=4\pi\bullet\frac{27}{4\pi}$

$=27\ km$

$Y_B:Y_A=4=1$

$SA_B:SA_A=16:1$

$432\div 16=27\ km^2$

$simple\ relation.$
