The smaller sector is 360-255=105 degree
it is 105/360 portion of the whole circle, and the area of the whole circle is πr², r is 14
so the area of the smaller sector is (105/360)*π*14²
run those numbers through your calculator, use 3.14 for π, you get 179.5
if you are looking for area of the larger sector, it would be
(255/360)*π*14²=435.94
Answer C cause I remember
Answer:
x= -8 x=2
Step-by-step explanation:
x^2 +6x - 6 = 10
Subtract 10 from each side
x^2 +6x -16 =0
Factor what 2 numbers multiply to -16 and add to 6
8*-2 = -16
8-2 = 6
(x+8) (x-2) =0
Using the zero product property
x+8 =0 x-2 =0
x= -8 x=2
Step-by-step explanation:
n(S) = 25
Assume that O : odd numbers and E : even numbers,
n(O) = 13
n(E) = 25-13 = 12
P(OO) = P(O) x P(O)
= 13/25 x 12/24
(because without replacing so the number of balls left decreases)
= 13/25 x 1/2
= 13/50
