He would be able to cut 4 pieces.
Answer:
area = 8a^2 +4ab
Step-by-step explanation:
Area = (4a)(2a + b)
= 8a^2 +4ab
4, there is 3 radii OA, OC and OB
2nd choice
5. there is one chord BC
first choice
6. 3 central angles:
AOC, AOB, BOC
first choice
This product could be zero if one or both of the parenthesis are zero.
3x-9=0; 3x=9; x= 3
5x-3=0; 5x=3; x=3/5
The solution is { 3/5, 3}
Area is square units, so the new area would be the scale factor squared:
Scale factor is 2, so the area would increase by 2^2 = 4
The answer is B.4
