B, D, and E are all correct. The line is coinciding.
The answer is
round cake - 82.42 in²
rectangular cake - 114 in²
Round cake:
d = 7 in
r = d/2 = 7 in / 2 = 3.5 in
h = 2 in
The surface are of a cylinder is:
A = 2πr² + 2πrh
The surface are of the round cake (which is actually a cylindrical cake) excluding the bottom is:
A = 2πr² + 2πrh - πr²
A = πr² + 2πrh
A = 3.14 * 3.5² + 2 * 3.14 * 3.5 * 2
= 38.46 + 43.96
= 82.42 in²
Rectangular cake:
w = 6 in
l = 9 in
h = 2 in
The surface are of a rectangle is:
A = 2wl + 2wh + 2lh
The surface are of the rectangular cake excluding the bottom is:
A = 2wl + 2wh + 2lh - wl
A = wl + 2wh + 2lh
A = 6 * 9 + 2 * 6 * 2 + 2 * 9 * 2
= 54 + 24 + 36
= 114 in²

Answer:
A
Step-by-step explanation:
<em>/Hello!</em>
<u><em>See below</em></u>
<em>We need to find x. X being the answer to 1/9 divided by 12.</em>
<em>1/9÷12=1/108. </em>
<em>Now that we know what "x" equals, we can divide the others.</em>
<em>1/9x12=1 and 3/9 ------simplifed is------1 and 1/3</em>
<em>Convert any mixed numbers to fractions</em>
<em>.</em>
<em>Then your initial equation becomes:</em>
<em>1/9×12/1</em>
<em>Applying the fractions formula for multiplication,</em>
<em>=1×12/9×1</em>
<em>=12/9</em>
<em>Simplifying 12/9, the answer is</em>
<em>=1 and 1/3</em>
This is not correct.
1/9×1/12
Applying the fractions formula for multiplication,
=1×1/9×1/2
=1/108
This is correct.
Therefore, your answer is B. 1/9 x 1/12
