Answer:

9 bags

Step-by-step explanation:

We need to find the area of the putting green with a radius of 30 ft

A = pi r^2

A = 3.14 (30)^2

A =2826 ft^2

Each bag will cover 315 ft^2

Divide the area by 315 ft^2 to determine the number of bags

2826/315 =8.971428571 bags

Rounding up to the nearest bag

9 bags
