The answer is 40 is 80% of 50
Answer:
the answer is A
Step-by-step explanation:
your trying to find surface area
Sphere volume = PI * diameter^3 / / 6=
PI * 9^3 /6 =
PI * 729 / 6 =
381.70
So, answer is A
Answer:
I got that AE^2 = 8EC^2
Step-by-step explanation:
Here's what I did. I probably did this wrong, but this might give you an idea on how to solve it.
First, create equations:
AB = BC = AC = DE = 2EC
BD= BC = EC
Then, I used pythagorean theorem (since AD is perpendicular to BC): AD^2 + DE^2 = AE^2
Substitute: (2EC)^2 + (2EC)^2 = AE^2
Simplify: 4EC^2 + 4EC^2 = AE^2
AE^2 = 8CE^2
