Answer:
The answer is 65.97 yd^3
Step-by-step explanation:
The volume of a cone is: v = 
So, v = 
(3^2)(7/3) = 65.97345 yd^3
Answer:
15
Step-by-step explanation:
5/15=3/v
5v=15×3
5v=75
5v/5=75/5
v=15
Answer:
Step-by-step explanation:
d + q = 94.....d = 94 - q
0.10d + 0.25q = 19.30
0.10(94 - q) + 0.25q = 19.30
9.4 - 0.10q + 0.25q = 19.30
-0.10q + 0.25q = 19.30 - 9.40
0.15q = 9.90
q = 9.90/0.15
q = 66 <===== there are 66 quarters
d + q = 94
d + 66 = 94
d = 94 - 66
d = 28 <==== there are 28 dimes
