please help me!!

zepp · Answer

Scale factor is 1 for 2, so if the larger solid has a side a 5, the large solid would have 10.
but the area would be different, let's say the scale factor is k, then the area scale factor would be $k^2$ and the volume scale factor would be $k^3$

zepp · Answer

And it's 'pi'

zepp · Answer

Thus, Area scale factor is 2^2 = 4
Volume scale factor is 2^3 = 8

$S=28 \pi cm^2 * 4 = 112 cm^2
V=20 \pi cm^3 * 8= 160 cm^3$
