The correct answer is
Triangle A
Triangle D
This is the answer because they are the same triangle but only triangle D is flipped upside-down.
volume of a cone = (1/3)*pi*r^2*h
180 = pi(r^2)h
180/pi(r*2) = h
the second one
Step-by-step explanation:
Answer:
2
Step-by-step explanation
8 times y <21. Well, what times 8 gives us less than 21. y is less than or equal to 2.
5x + 4 = 7x
Subtract 4 from both sides.
5x = 7x - 4
Subtract 7x from both sides.
5x - 7x = -4
Simplify.
-2x = -4
Divide both sides by -2.
x = 4/2
x = 2
