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:
A
Step-by-step explanation:
6/x* 5/(2x+1) = 30/ 2x^2+x
Answer:
V=1890mm
Step-by-step explanation:
You must use its formula: which is
V=(Length x height x width) / 3
V=(15x18x21)/3
V=5670/3
V=1890mm
