All of them except B and C. Probabilities must add to 1 and none of the p's can be negative
Answer:
25*pi or
78.5 square units.
Step-by-step explanation:
If there was no shaded area, the area of the circle would be pi * r^2
r = 10
Area = pi * 10^2
Area = 100 * pi
Since there is a shaded area, the shaded part looks to be 1/4 of the whole. There's no indication of what it actually is, but 1/4 should be close enough.
Area_shade = 1/4 (100*pi)
Area_shade = 25 * pi
That's one answer.
Another is 25 * 3.14 = 78.5 square units
Answer:
3:4:7
Step-by-step explanation:
14-(3+4)
=14-7
=7
red:white:blue
3:4:7
If one eighth of the pizza falls, that leaves seven eights of the pizza to be shared:

If the 7/8 pizza is shared between three people, then you have to divide 7/8 by 3. We know that dividing a fraction by 3 is the same as multiplying by 1/3:

Therefore, each person gets 7/24 of the whole pizza.
