Answer:
In order to answer this you would need to use this equation: <em>A = πr² </em> (See explanation)
Step-by-step explanation:
So, The circumference of the circle is 65n?
What you need to do is <em>A = πr² </em>
Let's divide 65n by Pi (65/3.14)
That equals 20.70n
Now we have the diameter of the circle. We need the radius for <em>A = πr² .</em>
We need to divide the diameter by two (20.70/2)
We now have the radius of the circle: 10.35n
Now we need to plug 10.35n in our Area equation :<em>A = π10.35² </em>
So now we multiply the Radius by Pi (π * 10.35)
This means that the area of our circle is: A = 32.49
Your answer Is 32.49n
Answer: x=6
Step-by-step explanation:
Do 4x+19x and that is 23x
And then do 12x+5x and that is 17x
Now the equation is 23x=36+17x
Now do 23x-17x and you get 6x
Now the equation is 6x=36
And then divide x by 6 and 36 by 6 and you get x=6
Answer:
a=41.8 BC=2.8
Step-by-step explanation:
sin30/6=sinx/8
8*sin30=6sinx
4=6sinx
sin^-1(4/6)
angle a
cosine rule
bc^2=3^2 +5^2-2(3)(5)*cos30
BC^2=
BC=2.83
2.8
Y - ( - 2) = - 3 ( x - ( - 3 )
This equation can also be simplified to
y + 2 = - 3 ( x + 3 )
