Final answer:
To calculate the area of a circle with a radius of 12.2 using π = 3.14, we use the formula A = πr² resulting in an area of 467.58 square units when rounded to the nearest hundredth.
Step-by-step explanation:
To find the area of a circle with a radius of 12.2 using π = 3.14, we use the formula A = πr².
Plugging in our values, we calculate the area as follows:
A = 3.14 × (12.2)²
A = 3.14 × 148.84
A = 467.5776
When rounding to the nearest hundredth, the area of the circle is 467.58 square units.
