Answer 2

It looks like you're trying to calculate the approximate circumference (C) of a circle with a radius (R) of 4.5 units and then an approximate circumference when R is approximately equal to 28.26 units.

The formula for the circumference of a circle is:

C = 2πR

1. For R = 4.5 units: C = 2π × 4.5 ≈ 2 × 3.14159 × 4.5 ≈ 28.27 units (rounded to two decimal places).

2. For R ≈ 28.26 units: C ≈ 2π × 28.26 ≈ 2 × 3.14159 × 28.26 ≈ 177.74 units (rounded to two decimal places).

So, the approximate circumferences for these values of R are 28.27 units and 177.74 units, respectively.
