Hello,
The formula for finding the circumference of a circle is
where r is the radius. SO we can plug 4 in for r in this formula because 4 is the radius:
. We are told to use 3.14 for 
so we get 
. Therefore, the circumference is 25.12 meters.
The formula for finding the circumference of a circle is
Answer:
r = 7.33 units
Step-by-step explanation:
Given that,
A cylinder has a radius of r units, and that the height of the cylinder is also r units.
The lateral area of the cylinder is 338 square units.
We need to find the value of r.
The formula for the lateral area of the cylinder is given by :
Put all the values,
So, the value of r is equal to 7.33 units.
