Answer:
The sprinkler does not reach <u>168.56 m²</u> of the field.
Step-by-step explanation:
Find the circular area sprayed by the sprinkler.
A	=	πr²	Use the formula.
A	=	π(14)²	Substitute. Use 14 for r.
A	≈	3.14 × 14²	Substitute. Use 3.14 for π.
A	≈	3.14 × 196	Evaluate the power.
A	≈	615.44	Multiply.
The area of the circular area is about 615.44 ft².
Find the area of the square field.
A	=	s²	Use the formula.
A	=	28²	Substitute. Use 28 for s.
A	=	784	Evaluate the power.
The area of the square field is 784 m².
Find how much of the field is not reached by the sprinkler. Subtract the circular area sprayed by the sprinkler from the area of the square field.
784 − 615.44	=	168.56
