Answer:
Perimeter of ABCD = <u>56 units</u>
Perimeter of WXYZ = <u>140 units</u>
Step-by-step explanation:
<u>To find the perimeter of ABCD, find the sum of all sides</u>
18 + 18 + 10 + 10 = 56
<u>To find the side lengths of WXYZ, use the equation:</u>
45/18 = 2.5
<em>You can also cross multiply to find the missing side lengths, but I'll show you this other way...</em>
<u>Multiply the pre-image side lengths by 2.5</u>
18 × 2.5 = 45
10 × 2.5 = 25
<em>45 and 25 of the new side length of WXYZ</em>
<em />
<u>To find the perimeter of WXYZ, find the sum of all sides.</u>
45 + 45 + 25 + 25 = 140
WX = 45, XY = 25, YZ = 45, ZW = 25

Answer:
236 cubic units (to 3 significant figures)
Step-by-step explanation:
volume of a cylinder = r²h (where r = radius and h = height)
Therefore, volume = x 5² x 3
= x 25 x 3
= 75
= 236 cubic units (to 3 significant figures)
Hi,
You just have to change z^25 to z^24 or z^27.
