b. If she bought 8.6 gallons of gasoline and 9 cans of oil, how much did she spend in all?
a. Choose an expression that represents the amount that Julie spent in all.
OA. 4.950.5.25g
OB. 4.959.5.25c
OC. 4.950 +5.25g
OD. 4.95g +5.25c

395.84

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
