Answer:
C
Step-by-step explanation:
The volume (V) of a sphere is calculated using the formula
V =
πr³
If the radius is doubled, that is r = 2r , then
V =
π (2r )³
(2r)³ = 8r³, thus the volume is multiplied by 8
If I understand the question, you have to get n alone. in this case, you have to subtract 7 from both sides, resulting in n (is less than) -10

Answer:
169.12
Step-by-step explanation:
I hope this is correct. First, you want to divide the semi-circle and the rectangle. To find the area of the rectangle, you do 16 x 9 to get 144. To find the area of the semi-circle, you do 3.14x16/2 to get 25.12. Then you want to add 144 and 25.12 to get 169.12. I hope this helps
