Answers:
a)
b)
Step-by-step explanation:
a) The area of the sector of a circle is given by:
(1)
and
(2)
Where:
is the radius
(3) is the length of arc
is the angle in radians
In this case we have to find the value of . So, let's begin substituting the known values in (1):
(4)
Isolating :
(5)
Substituting (5) in (3):
(6)
Solving:
(7) At this point we have , but we need to find the value of in order to have the actual value of the length of arc.
Making (1)=(2):
(8)
Isolating :
(9)
Substituting (7) and (5) in (9):
(10)
Finding :
(10) Now that we have the value of the radius, we can substitute it in (7) and finally find the value of the
(11)
(12)
b) In this second case we have:
is the length of arc
is the angle in radians
the radius
We have to find the area of the sector and we will use equations (1) and (2):
(13)
(14)
(15)
(16)
Knowing :
This is the area of the sector of the circumference.
The slope is the factor a in front of the x after rewriting in y = ax + b form.
Your equation becomes:
3y = 4x - 1 - 5
3y = 4x - 6
y = 4/3 x - 2
now you can see the slope is 4/3
Given:
Side length of a cube is units.
To find:
The equation for the volume of the cube.
Solution:
We know that, the volume of a cube is:
Where, a is the side length of the cube.
Putting , we get
So, the volume of the cube is cubic units.
Therefore, the correct option is A.
2 and 4 because 40 can go into 2 and4 also 4 is to plus 2
