Answer:
C. 314
Step-by-step explanation:
The volume of a cone is: 1/3h'
1/3 x 3.14 x x 12
1/3 x 3.14 x 25 x 12
1/3 x 3.14 x 300
100 x 3.14
V = 314
The answer is 314
You need to do
3.14(pie) times the radius times the height divided by 3
a = 20
7a + 2a + a − 9a = 20
Combine like terms
10a -9a = 20
a =20
helooooo :D
