2.1 squared is 4.41, 4.41 times 3.14 is 13.84, 13.84 times 4/3 is 18.46.
your answer is 18.46 cm3
Answer:
60.6528 kg
Step-by-step explanation:
Assuming the solid ball of iron is a sphere with a radius of 18 cm (or 0.18 m), we can compute the volume of the sphere:

Therefore, the volume of the solid ball is 0.007776 m³
Since we know that density is mass/volume, then we can find the mass of the iron:

Thus, the mass of the solid ball of iron is 60.6528 kg
so the answer is 2 for the question?
Answer:
<C = 133 degrees
Step-by-step explanation:
<B = 90 - 43
<B = 47
<C = 180 - 47
<C = 133 degrees
The rectangle with maximum area will actually be a square.
Each side will be of length 7/4 = 1 3/4.
