Hi there!
To find the unknown addend, we can just subtract:
1 - 2/6 = 4/6
4/6 = 2/3
Hope this helps!
Answer:
The density of the material must be at least 1.5 g/cm³.
Step-by-step explanation:
<span>So we want to know the volume V of the volleyball if we know the diameter d=8.15 inches and we need to round it to the nearest hundreth. The volume of a volleyball is V=(4/3)r^3*pi, and since 2 radius are equal to the diameter we need to get the radius, so 2r=D and r=D/2 or r=4.075 inches. Now we get the volume after inputting the numbers: V=283.303032 inches^3. Rounded to the nearest hundreth: V=283.30</span>
