Well I'm just doing some random math so it might be 300?
Lateral surface are = 2( 1/2 x 11 x 11.9) + 2( 1/2 x 9 x 12.3)
Lateral surface area = 130.9 + 110.7 = 241.6 ft²
Answer: 241.6 ft² (Answer C)
It goes 19 1 and 4ths to the area surface
Answer:
3.1
Step-by-step explanation:
19.9 = 9y - 8
+8 +8
27.9= 9y
/9 /9
3.1 = y
Check:
9(3.1) - 8 =
27.9 - 8 = 19.9
A is the best answer…
Work:
-10x-(-4y) will equal -10x+4y the minus minus will cancel out
