He gave away 2 of the 6 chocolate bars, so he gave away 2/6 or 1/3.
Answer: you failed unfortunately
Step-by-step explanation:
The volume of a sphere is:
V=(4pr^3)/3 so the initial volumes is:
Vi=(4p*4.5^3)/3=121.5p in^3 (before match, approx 381.7 in^3)
Vf=(4p*4.4^3)/3=340.736p/3 (after match, approx 356.8 in^3
Vf-Vi=24.9 in^3
So the ball lost about 24.9 in^3 of air during the match...
The reason that ABD and ACB are similar is because of ASA (angle-side-angle). They share both the line AB and two congruent angles, <C and <B.
