The answer is
D: 160π cm^3
50x30=1500 (this is an approximated rounded answer)
Answer:
Partition
Step-by-step explanation:
Partition in mathematics is a way of calculating maths problems that involve enormous numbers by halving or ranking them into smaller units so they’re straightforward to work with. For instance, rather than adding up digits in a column,
86
+32
118
You can rank these numbers into units, like this…
80 + 6 + 30 + 2
Rearrange and the tens up
80+30+6+2=118
You would have to find it in terms of single units:
Divide 44.88 by 12:
44.88/12= 3.74
Therefore, the cost per gallon of gas is $3.74
Remark
I take it the semicircles cover the full width of the paper.
So the radius is 12/2 = 6 cm
Since there are two of them, the area = a full circle.
Step One
Find the area of the rectangle before the cuts were made.
Area = L * W
L = 27
W = 12
Area = 27 * 12 = 324 cm^2
Step Two
Find the area of the circle cut outs.
r = 6
Area = pi * r^2
Area = 3.14 * 6^2
Area = 3.14 * 36
Area = 113.04 cm^2
Step Three
Find the total area left
Total Area Left = rectangle - circle
Total Area Left = 324 - 113.04
Total Area left = 210.96 cm^2 Answer
