The formula for the circumference of a circle is:
C = 2πr
Where C is the circumference, π is pi (approximately 3.14), and r is the radius of the circle.
Using this formula, we can plug in the given radius of 4 feet:
C = 2π(4)
C = 8π
Approximating π to 3.14, we get:
C ≈ 8(3.14)
C ≈ 25.12 feet
Therefore, the lens circumference of the telescope is approximately 25.12 feet.
The lens of a telescope has a radius of 4 feet what is the lens circumference use 3.14
