Answer:
A. 63.8 in^2
Step-by-step explanation:
The surface area of a cylinder is given by:
A=2πrh+2πr^2
2πr^2 gives the area of the 2 ends, each with area πr^2.
2πrh gives the suface area of the outside of the cylinder.
r = 0.4 inches
h = 25 inches
Area = 63.8 in^2
the sphere would fall over or be unbalanced on the cylinder, it doesn't have a flat surface where it can be balanced.
(unless you use glue or stick the sphere onto it :P)
Answer:
C
Step-by-step explanation:
The reason it is C because if the answer was A, then the 55 would have to have been the T since the T represents time in weeks. If it was B, look at explanation for A. It is basically the same reason why. It is not D because if he already the 55 dollars in his savings then the 55 would have been the B of the equation which right now is 120. By process of elimination, your answer should be C. Also the fact that Norman was depositing 55 dollars EACH week is a big help.
