Question

1. find π, when c = 44 cm and r = 7 cm

Explanation:

Step1: Recall the formula for the circumference of a circle

The formula for the circumference of a circle is \(C = 2\pi r\).

Step2: Solve the formula for \(\pi\)

We can rewrite the formula \(C = 2\pi r\) to solve for \(\pi\) as \(\pi=\frac{C}{2r}\).

Step3: Substitute the given values of \(C\) and \(r\)

Given \(C = 44\space cm\) and \(r = 7\space cm\), substitute these values into the formula \(\pi=\frac{C}{2r}\). So \(\pi=\frac{44}{2\times7}=\frac{44}{14}\).

Step4: Simplify the fraction

Simplify \(\frac{44}{14}\) by dividing both the numerator and the denominator by 2. We get \(\pi=\frac{22}{7}\approx3.14\).

Answer:

\(\pi=\frac{22}{7}\) (or approximately \(3.14\))
