Step-by-step explanation:
Hey, there!!
a. (-12)×(-11)×10
Here, (-)×(-)=(+)
(-12)×(-11)=132
so,
=132×10
=1320.
For b.
(-25)×(-8)×(-2)
(-)×(-)=(+)
(-25)×(-8)=200
so,
=200×(-2) { (+)×(-)=(-)}.
= -400.
Therefore, the answer of a. no. is 1320, and no. b is (-400).

Answer:
C. 28.6
, 0.28
Step-by-step explanation:
<em><u>To find the white portion's area, you add 44 and 47, then multiply it by π</u></em>
:
44 + 47 = 91
(3.14)
A = 28.574 → A = 28.6
<em><u>There are 7 parts of the circle, and 2 of them are white. So divide 2 by 7:</u></em>
2 ÷ 7 = 0.28
