The formula for the area of a circle is 

To break it up, its π×r×r=A
The radius is 12inches
So the equation is 3.14×12×12
3.14×12=37.68
37.68×12=452.16
452.16 rounded is 452
A=452inches

Answer:
The triangle ABC is an isosceles right triangle
Step-by-step explanation:
we have
The coordinates of triangle ABC are
A (0, 2), B (2, 5), and C (−1, 7) 
we know that
An isosceles triangle has two equal sides and two equal internal angles
The formula to calculate the distance between two points is equal to

step 1
Find the distance AB
substitute in the formula



step 2
Find the distance BC
substitute in the formula



step 3
Find the distance AC
substitute in the formula



step 4
Compare the length sides




therefore
Is an isosceles triangle
Applying the Pythagoras Theorem

substitute


 -----> is true
 -----> is true
therefore
Is an isosceles right triangle
