Part 1) we have that
volume smaller solid=512 cm³
volume larger solid=2197 cm³
we know that
volume larger solid=[scale factor]³*volume smaller solid
scale factor=∛[volume larger solid/volume smaller solid]
scale factor=∛[2197/512]-----> scale factor=1.625
Part 2)
the ratio of the surface areas is equal to [scale factor]²
1.625²-------> 2.64
Part 3)
surface area smaller solid=960 cm²
then
surface area larger solid=scale factor²*surface area smaller solid
surface area larger solid=[1.625]²*960-----> 2535 cm²
surface area larger solid is 2535 cm²
It would be the first one
Step-by-step explanation:
Well, first I split it up into two different equations:
6-4=2
5/8-2/9=.4027
Then, added the two: 2.4027
6.4x10^5 + 0.36x10^5 = 6.76x10^5, or 676,000
ANSWER: A 15 Pizza
50 x 0.3 = 15
30% = 0.3
