X=130
Step-by-step explanation:
Since the two sides are equal, the two angles are equal.
x=180-25-25
x=130
The answer is: " 1024π units² " ; or; " 3215.36 units² " .
______________________________________________________
A = π * r² ;
A = π * 32² = 1024 π units² ;
or, using "3.14" for "π" ;
1024 * π = 1024 * (3.14) = 3215.36 units² .
