Question

Use your knowledge of area and perimeter to complete the following problems. Use 3.14 for  and round to the nearest hundredths place, whenever necessary. Show all work.Part 1:A farmer bought 30 feet of fencing to build a circular pen for his pigs. What is the diameter of the pen he can build with 30 feet of fencing?The farmer also needs to buy a certain type of seed for the grass in the pen. Each bag of seed can cover 50 square feet of land. How many bags of seed will the farmer need to buy?

Answer 1

`\begin{gathered} \text{Circumfrence of the pen is,} \\ C=2\pi r \\ 30=2\pi* r \\ r=(30)/(2\pi)=4.77\text{ ft} \\ \text{The diameter is}\Rightarrow d=2r \\ d=2*4.77=9.55\text{ ft} \\ \text{Now, second problem} \\ \end{gathered}`
