The diameter of a circle is the distance across at its widest point (right through the center). The radius is the distance from any point on the circle to the center (which means it's half of the diameter. Since we know the radius of the manhole cover is 12 inches then...
diameter = 2 × r
diameter = 2 × 12
diameter = 24 inches
Answer:

Step-by-step explanation:
AB would be (n) * (2n + 6). We need to distribute the n, so we multiply the n by each term within the parentheses and add those products together:
AB = 
C is just
, and we subtract this from
:

Thus, the answer is
.
Hope this helps!
Multiply 199 by 355 to give you 70,645. Then add 70,645 to 1068 to give you 71,713.

The parameters for computing the area of triangle is first listed out and the expression for the area of triangle was used to find the algebraic method
<h3>Area of Triangle</h3>
Parameters for find the area of triangle are
Let the base be x, and let the height be y
We know that the expression for the area of triangle is given as
Area = 1/2 (Bass* Height)
Substituting our parameters we have
Area = 1/2*x*y
