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?
- The diameter is 2 meters
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]
