Question

2)
0.5 in
c=
a=

Explanation:

Step1: Calculate the circumference

The formula for the circumference of a circle is \(C = 2\pi r\).
Given \(r=0.5\) in, substitute into the formula: \(C = 2\times\pi\times0.5=\pi\approx 3.14\) in.

Step2: Calculate the area

The formula for the area of a circle is \(A=\pi r^{2}\).
Substitute \(r = 0.5\) in: \(A=\pi\times(0.5)^{2}=\pi\times0.25\approx 0.785\) in².

Answer:

\(C\approx3.14\) in, \(A\approx0.785\) in²
