Answer:
Joan is making a circular table cloth. It has a diameter of 2 meters. How many meters of lace are needed to decorate the sides of the table cloth?
1. What is asked in the problem?
- The meters of the lace are needed to decorate the sides of the table cloth.
2. What is the given fact or data?
3. What formula will you use to solve the problem?
[tex]\boxed{ \begin{array}{}\tt C = \pi \times d \end{array}{}}[/tex]
4. What is the mathematical sentence?
[tex]\boxed{ \begin{array}{}\tt 3.14 \times 2 \: meters = n\end{array}{}}[/tex]
5. How do you solve for the answer? Show
your solution and complete answer.
[tex]\boxed{ \begin{array}{}\tt C = \pi \times d \\ = \tt3.14 \times 2 \: meters \\ \tt C = 6.28 \: meters\end{array}{}}[/tex]
Final Answer:
6.28 meters of lace is needed to decorate the sides of the table cloth.
Step-by-step explanation:
- Remember the formula on finding the circumference of a circle with the given radius or a diameter:
- [tex] \tt C = \pi \: d \\ \tt C = 2\pi \: r [/tex]
