Surface area = PI x rL + PI x r^2
since the answer is in terms of PI, remove PI from the equation:
surface are = rl +r^2
r = 3 and l = 15
3*15 + 3^2 = 45 +9 = 54
answer is 54PI units^2
Answer is C
to translate coordinates in this manner, for each point perform the following:
add 5 to the original x coordinate
add 2 to the original y coordinate
option a is the answer
1. -3x -20
2. -6x-16
3. -14-x
Answer:
KM = 4 units
Step-by-step explanation:
mathematically;
since l is on line segment KM
KM = KL + LM
substituting values;
5x + 4 = 5x + 1 + 3x + 3
5x + 4 = 8x + 4
8x-5x = 4-4
3x = 0
x = 0
KM = 5x + 4 = 5(0) + 4 = 4 units
