The lens of a telescope has a radius of 4 feet what is the lens circumference use 3.14

1 answer

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.
