How would i start this off?
2. The height of one square pyramid is 12 m. A similar pyramid has a height of 9 m. The volume
of the larger pyramid is 64 m3. Determine each of the following, showing all your work and
reasoning:
a.) Scale factor of the smaller pyramid to the larger pyramid in simplest form
b.) Ratio of the areas of the bases of the smaller pyramid to the larger pyramid
c.) Ratio of the volume of the smaller pyramid to the larger pyramid
d.) Volume of the smaller pyramid

Best ResponseYou've already chosen the best response.0scale factor smaller to larger = 1: 12/9

Best ResponseYou've already chosen the best response.0Do you reduce after that too because it says simplest form?

Best ResponseYou've already chosen the best response.0yes i guess it would be better to write it as 9:12  now divide both numbers by 3 to give 3:4

Best ResponseYou've already chosen the best response.0now the ratios of the area will be the squares of these number 3^2 : 4^2

Best ResponseYou've already chosen the best response.0So it's the simplest form of the scale factor and then you square those numbers

Best ResponseYou've already chosen the best response.0yes  i leave you to work out the squares then the volume ratio will be 3^3 : 4^3

Best ResponseYou've already chosen the best response.0to find the volume of the smallest pyramid you can wirite 2 fractions dw:1433873539452:dw

Best ResponseYou've already chosen the best response.0So like the ratio would be 3^3 which would be 24 and 4^3 which would be 64 for c?

Best ResponseYou've already chosen the best response.0no your calculations are wrong somewhere its eas y if you write it this way dw:1433874159799:dw
