Answer:
<em>D.1767.1 in³</em>
Step-by-step explanation:
<em>volume of a sphere=4/3πr³</em>
<em>where r=radius of the sphere</em>
<em>Given diemeter= 15in</em>
<em>so radius=15/2=7.5in</em>
<em>volume=4/3×π×(7.5)³</em>
<em>=4/3×22/7×(7.5)³</em>
<em>=1767.1in³</em>
<em>hope it helps...</em>
<em>have a great day!!</em>
