Dale is spreading grass seed over the putting green on a golf course. The circular green is centered about the cup with a radius of 30 feet. If each bag of grass seed covers 315 ft^2, how many bag(s) of grass seed does Dale need? QUESTION FROM MATH NATION!!!

Respuesta :

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

Answer:

9 bags

Step-by-step explanation:

Total area = 3.14 × 30²

= 2,826

No. of bags:

2,826/315

= 8.9714285714

To cover the area, he needs 9 bags
