Answer: Choice A) cone
One way to picture this is to think of a propeller. As the propeller spins, it carves out a 3D space even though the blade is "2D" in a sense.
If we spin everything around segment BC, we get a 3D cone forming. The base of the cone is vertical and it has a radius of AC. The height of the cone is segment BC. It might help to rotate the paper 90 degrees clockwise so that BC is vertical.
the answer is 8
Step-by-step explanation:
4 + 4=8
double the number
$900+ $288( interest after 8 years)= $1, 188( total balance)
I believe the answer is
26
sorry if wrong
if not an answer choice then 168.
