Question 86332: HELP PLEASE!! I AM CONfusED to DEATH. it will be greatley appreciated
One triangle has area 126 and base 12. Find the area of a similar triangle with base 16

area of triangle 1 A1=126 base=b1=12 area of triangle2 = ? if base= b2=16
a1=1/2b1.h1 h1=2a1/b1=2.126/12 = 21 h1=21
area of triangle A2 = 1/2.b2.h2 but h1=h2 (similar triangles)
= 1/2.16.21
=168

Two similar cones have scale factor 5:2. If the total area of the larger cone is 375, find the total area of the smaller cone.

area of acube= l^2 volume of a cube = l^3
A1/A2=40.5/72 =405/720=81/144.L1/L2=9/12
V1/v2=9/12.9/12.9/12= 729/1728.
Two cubes have total areas of 40.5cm squared and 72 cm squared. What is the ratio of their volumes?
