Area = 3.14*(12.5^2 - 3.5^2)/4 =113.04
Answer is B
Answer:
50
Step-by-step explanation:
to find the value of x use "sinerule"
sinx/13= Sin90/17
sinx = sin90×13/17
sinx= 14/17
sinx= 0.764705882
X= SIN^-1(0.764705882)
X = 49.888
X= 50
We know that the volume of a sphere is:
V
=
4
3
π
r
3
where
r
=
10
2
=
5
ft
is the radius;
we need half of this, so we use:
V
2
=
2
3
π
r
3
=
261.8
ft
3
giving a total weight of water of:
W
=
261.8
⋅
62.4
=
16
,
336
pounds
In completing the square, the first step is to factor out the first and second term so that the factor (x+a) is highlighted. This is seen in line 1. However, in line 2, the subtracted value should be 3 so as to compensate for the added value. This affects then line 3 as well. The answer is line 2.
