Answer:
the volume is 

Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a cylinder.
Given data
Volume v = ?
Radius r = r in
Height h= 2r in
We are expected to solve for the volume of a cylinder, given the above data we can substitute it in the formula for volume of a cylinder to obtain our result
we know that the expression for the volume of a cylinder is


Hence the volume in terms of the radius is 
Answer:
60cm^2
Step-by-step explanation:
15 times 8 = 120
divided by 2 = 60
Answer:
18.84cm
Step-by-step explanation:
There is a formula which for the diameter is pie (3.14) times the diameter. Now if you have the radius it would be pie (3.14) times 2 times whatever the radius would be. Now you could use either formula for this, just divide the diameter by two to get 3.
So 3x2x3.14=18.84cm
So then you could just multiply 6x3.14 and still get 18.84cm
Answer:
48
Step-by-step explanation:
3 times 13 (john's age) = 39
39 + 9 = 48 (nine years older than 3 times (39) so you add 9)
Therefore, Tim is 48.
