Step-by-step explanation:
Use the formula:

V = 7599, h = 20, π = 3.14
Plugin the numbers and solve for r

8: slope is 1/2 and y intercept is 0

Answer:
20x-10
Step-by-step explanation:
Cows have
legs and 3 toes on each leg, if we want to find the number of toes of ONE cow we have to multiply the legs by the toes giving the following:

But we have two cows so (1) we have to multiply it by 2 giving a total of:

By the other hand chickens have
legs and 7 toes on each leg, if we want to find the number of toes we have to multiply the legs by the toes giving the following:

To find the total amount of toes we have to add (2) and (3)


So, the answer to this problem is
x = 9/2 or
x = 4.5.
