A cone and a triangular pyramid have a height of 9.3 m
and their cross-sectional areas are equal at every level
parallel to their respective bases.
What is the height, x, of the triangle base of the
pyramid? Round to the nearest tenth
9.3 in.
6
in.

Step-by-step explanation:

The complete question is

A cone and a triangular pyramid have a height of 9.3 m  and their cross-sectional areas are equal at every level  parallel to their respective bases. The radius of the base of the cone is 3 in and the other leg (not x) of the triangle base of the triangular pyramid is 3.3 in

What is the height, x, of the triangle base of the  pyramid? Round to the nearest tenth

The picture of the question in the attached figure

we know that

If their cross-sectional areas are equal at every level  parallel to their respective bases and the height is the same, then their volumes are equal

Equate the volume of the cone and the volume of the triangular pyramid

simplify

we have

substitute the given values

solve for x

How many people are we starting with? i will answer it's just i need to divide 8 by the total amount of people to get how many tables

Ithink it's b sorry if i'm wrong
