Use cavalieri’s principle to compare the volume of the cone and triangular pyramid.

Cavalieri principle states that:

" If, in two solids of equal altitude, the sections made by planes parallel to and at the same distance from their respective bases are always equal, then the volumes of the two solids are equal "

Hence here the given two solids are cone and triangular pyramid.

Hence if the two solids have same altitude or height, the sections made by planes parallel to and at the same distance from their respective bases will be equal then the volume of the given two solids will also be equal.

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

gmt is 4 hrs ahead of edt so just add four hours to 1: 14: 20 (minutes and seconds stay the same)

gmt is 5: 14: 20

hope this !
