Final answer:
The formula for finding the area of a circle is A = πr². Using this formula, the area of a circle with a radius of 1.2 m is 4.5238934 m², which rounds to 4.5 m² when limited to two significant figures.
Step-by-step explanation:
The formula for the area of a circle is A = πr², where A represents the area and r represents the radius. To find the area of a circle, you can use the formula A = π(1.2 m)². Plugging in the value for the radius, you get A = 3.1415927... × (1.2 m)² = 4.5238934 m². Since the radius has two significant figures, the calculated quantity is limited to two significant figures, so the final answer is A = 4.5 m².
