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
Answer: x= -7, y= 0
Hope this helped , if it did mark me brainliest pls!
Your answer should be 314
4 x 16=64
10 x 25 (25 is the height)=250
64 + 250=314
