Final answer:
To convert the circumference of a woman's basketball from inches to centimeters, multiply by 2.54 (28.5 inches × 2.54 = 72.39 cm). Rounded to two significant figures, the circumference is 72 cm.
Step-by-step explanation:
The question asks us to convert the circumference of a woman's basketball from inches to centimeters, and the maximum weight from ounces to grams.
Using standard conversion factors, we know that 1 inch is equal to 2.54 centimeters and 1 ounce is equal to 28.3495 grams. To convert the circumference from inches to centimeters, we multiply by 2.54: 28.5 inches × 2.54 cm/inch = 72.39 cm. This can be rounded to two significant figures as 72 cm, because the starting value is given to three significant figures, and the conversion factor is known to more than two significant figures, which doesn't limit our result. The maximum weight of 20 ounces is converted to grams by multiplying by 28.3495 g/oz, which equals 567 grams. However, since we want two significant figures, we round it to 570 grams. The options provided in the question do not include the weight in grams, therefore we will address only the circumference portion.
The correct option for the circumference of the basketball in centimeters, rounded to two significant figures, is (b) 72 cm.
