Cross multiply
4/p=11/2
(4)*(2)=11*p
8=11p
Flip the equation
11p=8
Divide both sides by 11
11p/11=8/11
p=8/11
hope this helps!
Answer:

Step-by-step explanation:
Let the variable be taken as 'r'.
Then, by raising it to the 7th power, we'll get the result as 

Now, by doubling the result....


If each of them cost $29.95 and you but four of them the formula you use is
29.95 x 4 = 119.80
The volume of a cylinder is represented by:

We know that r is equal to

, and d in this case is 9 in. Therefore, r = 4.5 in.
Then, using 3.14 for

, and 15 in. for height, we can solve for the volume of the cylinder:



By using this equation, we were able to determine that the volume of this cylinder is
.
