?

1.83 × 10³ cm²

Explanation:

Step 1: Given data

Surface area of a NBA basketball (A): 283 in²

Step 2: Convert "A" from square inches to square centimeters

In order to convert "A" from in² to cm², we need a conversion factor. In this case, we will use the conversion factor 1 in = 2.54 cm. Since "in" is raised to the power of 2, we will have to raise the conversion factor to the power of 2 as well.

283 in² × (2.54cm/1 in)² = 1.83 × 10³ cm²

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or
