CIRCUMFERENCE OF A CIRCLE
Answer:
Problem: What is the circumference of a garden table with a diameter of 15 cm?
- Answer: [tex] \bold{\color{green}{\large 47.1 \ \ cm}} [/tex]
Formula:
The formula for finding the circumference of a circle is:
- [tex] \begin{gathered}\boxed{\begin{array}{l} \large {\boxed{\rm{\color{darkgreen}{C = 2 \pi r}}}} \ \rm or \ {\boxed{\rm{\color{darkgreen}{C = \pi d}}}} \end{array}}\end{gathered} [/tex]
Given/s:
The diameter of the garden table is 15 cm.
- Diameter (d) = 15 cm is the diameter of garden table.
Find the circumference of the garden table!
Solution:
The formula: [tex] \large {\boxed{\rm{\color{darkgreen}{C = \pi d}}}} [/tex]
- [tex] \large \rm C = \pi d [/tex]
- [tex] \large \rm C = (3.14) (15 \: cm) [/tex]
- [tex] \large {\boxed{\rm{\color{darkgreen}{C = 47.1 \: cm}}}} [/tex]
Therefore, the circumference of the garden table is [tex] \bold{\color{green}{\large 47.1 \ \ cm}} [/tex]
