Symmetry means that if you split it in half, the two sides would be equal. For example, the letter X is symmetrical.
Put the given information into the formula and solve for the variable of interest.
.. V = π*r^2*h
.. 252π = π*r^2*7
.. (252π)/(7π) = r^2
.. 36 = r^2
.. 6 = r
The radius is 6 cm. Selection D is appropriate.
_____
We would prefer that the offered selections had the appropriate cm units attached.
3d + 4 = 2 + 3d - 1/2
3d + 4 = 1 1/2 + 3d |subtract 3d from both sides
4 = 1 1/2 FALSE
Answer: No solution ( x ∈ ∅ )
