The square inches of paper Ray needs are equal to the area of the sides he wants to cover.
<h3>What is the area?</h3>
The area of an object refers to the surface or space occupied by the object.
<h3>Why is the area important?</h3>
In this situation calculating the area is essential because by doing this, Ray can know how much paper he needs.
<h3>How to calculate the area?</h3>
Different formulas can be used to calculate the area depending on the shape of the object.
- Rectangle: Side x side
- Triangle: 1/2 base x height
- Circle: πr2
This means to know the exact answer, Ray needs to calculate the area of the sides he wants to cover and this is equal to the paper he needs to buy.
Note: This question is incomplete because the picture was not attached. Due to this, I answered it based on general knowledge.

Answer:
2440.24 J
Explanation:
Moment of inertia, I1 = 5 kg m^2
frequency, f1 = 3 rps
ω1 = 2 x π x f1 = 2 x π x 3 = 6 π rad/s
Moment of inertia, I2 = 2 kg m^2
Let the new frequency is f2.
ω2 = 2 x π x f2
here no external torque is applied, so the angular momentum remains constant.
I1 x ω1 = I2 x ω2
5 x 6 π = 2 x 2 x π x f2
f2 = 7.5 rps
ω2 = 2 x π x 7.5 = 15 π
Initial kinetic energy, K1 = 1/2 x I1 x ω1^2 = 0.5 x 5 x (6 π)² = 887.36 J
Final kinetic energy, K2 = 1/2 x I2 x ω2^2 = 0.5 x 3 x (15 π)² = 3327.6 J
Work done, W = Change in kinetic energy = 3327.6 - 887.36 = 2440.24 J
DNA in all humans are composed of the same stuff just not the same genes (basically) . Organisms like sea animals for example wouldn't have the same DNA with us because they havebto survive in a different environment and have to have special obillities
