circumference of circle: 2πr ("r" is the radius)
==========
Answer:
15.7 cm²
Step-by-step explanation:
Given:
[tex]\text{Radius of circle: 2.5 cm}[/tex]
Formula:
[tex]\text{Circumference:} \ 2\pi r[/tex]
Substitute the radius in the circumference formula:
[tex]\implies \text{Circumference:} \ 2\pi r[/tex]
[tex]\implies \text{Circumference:} \ 2\pi (2.5)[/tex]
Take π as 3.14 (Approx. value of π):
[tex]\implies \text{Circumference:} \ 2(3.14)(2.5)[/tex]
Simplify the circumference:
[tex]\implies \text{Circumference:} \ (3.14)(5)[/tex]
[tex]\implies \text{Circumference:} \ 15.7 \ \text{cm}^{2}[/tex]
