To find a volume of a cylinder we use the following formula:

Plug in the values:

Take the square:

Multiply the numbers:
Answer:
384, 216, 290, 192, 384
1446, 1 roll
Step-by-step explanation:
For rectangular boxes, calculate the sum of each side, then multiply it by two.
Box 1: 2(18 x 5) + 2(18 x 4) + 2(5 x 4) = 364
Box 3: 2(11 x 8) + 2(8 x 3) + 2(3 x 11) = 290
Box 5 is a cube (all sides equal), so you can find 1 side's area and multiply it by 6.
Box 5: 6(8 x 8) = 384
For triangular boxes, calculate the edges, then find the triangular area using area = 0.5(base x height).
Box 2: (15 x 3) + (9 x 3) + (12 x 3) + 2(0.5)(9 x 12) = 216
Box 4: 2(13 x 2) + (10 x 2) + 2(0.5)(10 x 12) = 192
Total: 364 + 290 + 384 + 216 + 192 = 1446
Rolls of wrapping paper:
Area of 1 roll = 30 x 60 = 1800
Since 1446 is less than 1800, you only need 1 roll of wrapping paper.
Answer:
Is that a magic spell??
Step-by-step explanation:
???
The midpoint of a line divides the line into equal segments.
The option that proves PQ = LO is (a)
The given parameters are:




P is the midpoint of LM.
So, we have:



Q is the midpoint of NO.
So, we have:



Distance PQ is calculated as follows:

This gives:



Distance LO is calculated as follows:



So, we have:


Thus:

Hence, the correct option is (a)
