Answer:
Cube root of 1446
Step-by-step explanation:
The formula for the volume of a sphere is 
. Therefore, if we divide 1928pi by 4/3pi and then take the cube root, you will find the radius. In this case, 1928pi/(4pi/3)=1446, meaning that the radius is the cube root of 1446. Hope this helps!

10% = £120
Then add it onto the original amount
£1200 + £120 = £1320
