Question

A circle has radius 54.5cm. Use π≈3.14 to approximate its circumference and area.

Answer 1

Step-by-step explanation:

The circumference and area of a circle can be calculated as

`\begin{gathered} \text{Circumference = 2}\pi r \\ \text{Area}=\pi r^2 \end{gathered}`

Where π = 3.14 approximately and r is the radius of the circle. Replacing r by 54.4 cm, we get:
