Answer:
V= πr²h
V= 72π
V= 226.2
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a cylinder
Given data
Radius r of cylinder 3
Height h of cylinder 8
We know that the volume of a cylinder is given as
V= πr²h
Substituting our given data we have
V= π3²*8
V= π9*8
V= 72π
V= 226.2
Answer:
Step-by-step explanation:
if t varies inversely proportional as r, then,
t ∞ 1/r
t = k.1/r
t = k/r
substitute t =6 and r = 5 into the equation above
6 = k/5
k = 5 x 6 = 30
the equation that represents this variation is given by,
t =30/r
tr = 30
when r =15,
t = 30/15
t =2
