Surface = 2 x PI x r x H + 2 x PI x r^2
= 2 x r x h + 2 x r^2
= 2 x 6 x 12 + 2 x 6^2
= 144 + 72
= 216 PI in^2
Answer is A
Answer: The answer is C
Step-by-step explanation:
A=16x²-8x+1
16x²-8x+1=l²
(16x²-4x)-(4x+1)=l²
4x(4x-1)-1(4x-1)=l²
x=1/4 or 1
Therefore
since x=1/4
l²=1/4=>l=>√(1/4)
l=1/2
since x=1
l²=1=>l=>√1
l=1
Therefore the length of each sides
1 or 1/2
Answer:
3/4, and 6/8
Step-by-step explanation:
3/4 = 9/12 simplfied
6/8 = 3/4 times two
