Final answer:
The area of a circle with radius 4.9 cm is roughly 75.36 cm². This is calculated using the formula for the area of a circle, which is πr².
Step-by-step explanation:
The area of a circle is calculated by using the formula: Area = πr², where r is the radius of the circle. In this case, the radius (r) is 4.9 cm. Hence, by substituting the value of r in the formula, we get Area = π*(4.9)² = approximately 75.36 cm².
