Answer:6.3 in.
Step-by-step explanation:
Given
Radius of sphere 
When ball is immersed in beaker, it causes the water to flowout of beaker which is collected in the conical vessel
Such that amount of water equivalent to sphere volume is collected in it.
volume of ball



Now volume of water collected is in shape of cone then volume of cone

and 
![\frac{256\pi }{3}=\frac{\pi }{3}(4)^2\times h\ quad [\text{h=height of cone formed}]](https://tex.z-dn.net/?f=%5Cfrac%7B256%5Cpi%20%7D%7B3%7D%3D%5Cfrac%7B%5Cpi%20%7D%7B3%7D%284%29%5E2%5Ctimes%20h%5C%20quad%20%5B%5Ctext%7Bh%3Dheight%20of%20cone%20formed%7D%5D)

4y²x(xy-2x²)=4y³x²-8y²x³
Answer:
307cm sq
Step-by-step explanation:
The area of the rectangle is 18x10 = 180.
The area of the semicircle is..
18/2= 9
3.14x9x9= 254.3
254.3/2 = 127.1
Overall, the area is....
127+180 = 307cm sq
Cheers!!
