So, r' (the new r) becomes kr, and h'=h*k,
so V' = pi * (r')^2*h' = pi * (r*k)^2*(h*k) = pi*r^2*h*k^3 = V * k^3

Answer:
the answer would be p= 15
Step-by-step explanation:
Answer:
Density of steel = 80.73 gm/
Step-by-step explanation:
The figure is made up of cuboid and square pyramid.
Height of cuboid, h = 9 cm
Length of cuboid, l = 6 cm
Width of cuboid, w = 6 cm
Volume of cuboid is given by the formula:


Density of Wood ,
= 0.68g/
We know that formula of Density is:


Putting the values:

Total weight = 
970 = 220.32 
= 749.68 gm
Volume of pyramid is given as:

Base is a square with side 6 cm

Density of Steel/Pyramid:

Answer:
x = 44
Step-by-step explanation:
4+4+2x+2x= 96
-(add like terms)
8+4x=96
-(subtract 8 from both sides)
4x=88
-(divide by 4 on both sides to get you x alone)
x=44
It is less than 2. I hope this helps!
