Answer:
Step-by-step explanation:
Based on the information provided, you know that the dimensions of the water tank John buys are:
Then, in order to find the expression that represents the volume of the water tank, you need to multiply those dimensions.
You must remember the Product of powers property, which states that:
Therefore, applying this property, you get that the expression that represents the volume of the water tank is:
By definition of , we have
and we deduce
Now, recall that the diameter is twice the radius:
and solve for :
So, divide the circumference by and you'll find the radius.
192/4=48
