Answer: Option C.
Step-by-step explanation:
You must use the formula for calculate the volume of a cone, which is shown below:

Where <em>r</em> is the radius and <em>h </em>is the height.
Based on the figure attached:

Substitute these values into the formula for calculate the volume of a cone, then the result is:

≈66in³
Answer:
142 cm^2
Step-by-step explanation:
2(L*H)+2(L*W)+2(W*H)=SA
7*3=21
21*2=42
7*5=35
35*2=70
5*3=15*2=30
30+70+42=142
Answer:
34
Step-by-step explanation:
because line BC divides line DA and line AE into parts with the same ratio to each other (since BC is parallel to DE). This means that (42/21)*17 will give us the length of AB, when we do so, we get 34 as the length of AB.
