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
Answer:
Step-by-step explanation:
This question is weird but my guess is C. You do need to create formulas.
32 empty square pieces are empty because the total number of squares in the board is 8X8 which is 64 and for the spaces filled theres 16 for each player and there are two players so its 16x2 which us 32. The total number of soaces minus the filled spaces will give you the number of empty spaces. So 64-32=32
1 yd 2 ft
* 8
----------------
8 yd 16 ft
but we can reduce 16 ft
there are 3 ft in a yd
16/3 = 5 yds with 1 left over
8 yds 16 ft = 8 yds + 5yds 1 ft
13 yds 1 ft
