The surface area of a cone with radius r units and slant height s units is shown below: surface area = 3.14(rs + r2) part a: if r = 6 units and s = 4 units, write an expression that can be used to calculate the surface area of the cone. (4 points) part b: what is the surface area of the cone? show your work. (6 points)

Part A: 3.14(6*4 + 6^2)

Part B: 188.4

Step-by-step explanation:

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw
