I would the $40-$20 and then get my answer it might be wrong so don’t get mad at me
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
Step-by-step explanation: This answer is not mine but JcAlmighty’s so all credits go to them.
5 1/3 - 3 2/6 simplify is 2.
Answer:
I believe the answer is B
Step-by-step explanation:
Supplementary means they equal 180°. There for out of the answer choices, the most logical would be b. 65°
115+65=180°
Hope this helps!
72 = 2 * 2* 2 * 3 * 3
120 = 2 * 2 * 2 * 3 * 5
The greatest common factor (GCF) would be gotten from the factors common to both 72 and 120.
The common = 2 * 2 * 2 = 8
The GCF = 8
