Answer:
1. area of new pen = 11
2. i. 5 feet by 2 feet
ii. 2 ½ feet by 4 ½ feet
Step-by-step explanation:
The size of the pen as planned = 5 ft long by 4 ½ ft wide
Area of the pen = length x width
= 5 x 4 ½
= 5 x
Area of the pen =
= 22 ½
But, Krista has to make the pen ½ the size of planned. So that;
area of new pen = ½ x 22 ½
= ½ x
=
= 11
area of new pen = 11
The area of the new pen would be 11 .
The possible values she could use are:
i. 5 feet by 2 feet
ii. 2 ½ feet by 4 ½ feet
In fact the mass of Sphere 2 will be 2³ = 8 times the mass of Sphere 1 (both spheres are steel and therefore will have the same density).
Therefore, since they were both steel then the larger one would have a mass of 2^3 or eight times the smaller (v is proportional to r^3). So the larger one would have an I 8*4 or 32 times the smaller one.
We let M equal to the mass of the first sphere then the mass of sphere 2 will be 8M and your calculation will result in this:
I2 = 2/5 (8M)(2R)² = 2/5 8M 4R² = 32(2/5 M R²)
so ration I2/I1 = 32.
