Problem #1
A groundskeeper needs grass seed to cover a circular field, 580 feet in diameter.
A store sells 100-pound bags of grass seed. One pound of grass seed covers about 800 square feet of field. What is the smallest number of bags the groundskeeper must buy to cover the circular field? Explain or show your reasoning.

Step1: Find the area of the circular field.

Step2: Find how many square feet covers a 100-pound bag(1pound covers 800 sq. ft)

Step 3: Find how many bags are needed to cover the entire area found on step1?

Step 4: Make sure to tell the number of bags that you need to cover the entire area of the field.
