The area of a circle is defined as Pi R^2
Since we only have the diameter and Pi, we need to solve for the radius.
The radius is 1/2 of the diameter, so divide 6 by 2 to get our radius.
6 / 2 = 3
Our radius is 3.
Now let's plug in our formula.
A = 3.14 x 3^2
3 x 3 = 9
9 x 3.14 = 28.26
Your area is 28.26 units ^2
I hope this helps!
Hello. In <span>x3 − 11x2 + 24x = 0 please use the symbol " ^ " to denote exponentiation:
</span><span>x^3 − 11x^2 + 24x = 0
First step: factor out x:
</span>
x^3 − 11x^2 + 24x = 0 = x(x^2 - 11x + 24) = 0
Second step: factor the polynomial x^2 - 11x + 24 = 0.
We can see right away that (-3)(-8) = + 24 and that
-3
-8
---
is equal to -11. Thus, the factors of
x^3 − 11x^2 + 24x = 0
are x(x-3)(x-8) = 0. The solutions are 0, 3 and 8.
Answer:
The length around the figure in terms of r is 2r (
+ 4).
Step-by-step explanation:
The perimeter of an object is the total length of the boundary of the object.
The figure consists two similar semicircle and a rectangle.
Adding the two semicircles, a complete circle is formed. The circumference of a circle = 2r.
The rectangle has a length which is twice its height.
i.e l = 2h
But,
r = 
(the diameters of the semicircles equal the height of the rectangle)
⇒ h = 2r
Thus, one side length of rectangle = 2 × 2r (l = 2 × h)
= 4r
The length around the figure in terms of r is:
= 2r + 4r + 4r
= 2r + 8r
= 2r ( + 4)
The length around the figure in terms of r is 2r ( + 4).
The x coordinates will stay the same. the y coordinates will be opposite.
