Answer:
A= 81πm² or 254.47 m²
Step-by-step explanation:
Area = π x r²
π x 9m² (9x9)
<em>i'm not 100% sure this is correct so i'm sorry if it is wrong</em>
Alternate interior angles are congruent. Therefore, set the two angles equal to each other and solve for x.
3x+4= 115
3x+4 -4 = 115 -4
3x = 111
x= 111/3---> 37. Therefore, x = 37.
Answer:

Step-by-step explanation:
Use coordinates (2,1) and 3,10
The exponential equation is

Plug in the x and y values.xfor both functions of coordinates.


Divide the equation with the larger exponet by the other equation.

Substitute that in for one of the equations.

Solve for a.


So our exponetial equation is
