Answer:
Step-by-step explanation:
![\frac{x^{3} }{\sqrt[6]{x}}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B3%7D%20%7D%7B%5Csqrt%5B6%5D%7Bx%7D%7D)
Volume of a ball = (4/3)πr³
When r = 18cm, V = (4/3)×3.14×18³ =24416.64 cm³
When r = 12cm, V = (4/3)×3.14×12³ =7234.56 cm³
Difference = 24416.64 - 7234.56 = 17182.08 cm³
the volume of air in the larger ball is <span>17182.08 cm³ greater than smaller ball </span>
Answer:
56 feet
Step-by-step explanation:
Perimeter is what the sum of all sides lengths of a polygon is. So if the retangle measures 13x15 feet, the perimeter would be 13+13+15+15. Because the 13x15 is only two sides, and a retangle has 4 sides. So we need to incorperate the other two sides, which are the same as the others because it is a retangle.
Hope this helps!
Answer: A
Step-by-step explanation:
The shape in the diagram is a square, a square is a shape with all sides being equal. To find out the length of all the sides, just count how many units make up one side since they're the same.
