Answer:

A ≈ 1313.19

Step-by-step explanation:

By using the formula A = 2  \pi r h + 2 \pi  r^{2} we can just fill in the information with what we know, which is Diameter = 22, Radius = Diameter/2 = 11. The height is 8. So in doing so we get A = 2\pi (11)(8)+2\pi (11)^{2}, which
equals ≈ 1313.18573.

Anyone know the area?

Answer:  The area of the triangle is:  " 8.5 cm² " ; 

                                         or, write as:  " 8\frac{1}{2} cm² " .
_______________________________________________________
Explanation:
_________________________________________________________
The formula {"equation"} for the area of a triangle is:

A = (\frac{1}{2}) * b * h ;
   
in which:  A = area; 
                 b = base;
                 h = [perpendicular] height;
___________________________________
{also, can be written as:  " A = (b * h) / 2 " .}.
______________________________________
Solve for the area, "A" ; by plugging in the known values shown in the figure (image attached):
______________________________________
                             base, "b" = 13 cm ;
[perpendicular] height, "h" =  5 cm ;
______________________________________
A = (b * h) / 2 ;

   = (13 cm * 5 cm) / 2 ; 

   = [ (13 * 5) cm²] / 2 ; 

    = 65 cm² / 2 ;

A  = " 8.5 cm² " ; or, write as:  " 8\frac{1}{2} cm² " .
_________________________________________________________
Answer:  " 8.5 cm² " ; or, write as:  " 8\frac{1}{2} cm² " .

Answer:

C. 7790.83 cm^3

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

We know the radius is 12.3

Using 3.14 for pi  (This will give us an approximation, not an exact value)

V = 4/3(3.14) (12.3)^3

   =7790.82984 cm^3
