Answer:

(1436.8cm³)  let me know if that helps

Step-by-step explanation:

-so if the diameter is a straight line and it's 15 cm

-The formula for the sphere it would be v=4/3πr³

-The radius is going to be r=7cm

-v = 4/3 π (7cm)³

-so you would type in 4/3 x 3.14 x 7 ³ =1,436

  - 3.14 or π

- you would round it to the nearest 10th (1436.8cm³)
