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:
1/7
Step-by-step explanation:
There are seven people in all on person will arrive at a different time than others. Every single one of them arrives at different times so it's 1/7
I believe this would be 5x/2x-5
Hope this helps!
The answer is -8 the angles of the triangle are 180 so
180=42+x+76+x+78
180=2x+196
2x=-16
x=-8
Answer:
V= 160pi or V= 502.65
Step-by-step explanation:
V = pi × r^2 × h
V = pi × (4)^2 × 10
V = pi × 16 × 10
V= 160pi or V = 502.65
