The working out would be-
Pi x radiussquared
Pi x 64 = 201.0619298297468
Rounded to 2 decimal places =
201.06 feet2
Answer:
Sorry but the correct answer is (x+3)2+(y−1)2=81
Step-by-step explanation:
Because the radius squared is the answer of the equation
-10(1) = w + 5.3
-10 = w + 5.3
-10 (-5.3) = w + 5.3 (-5.3)
w = -15.3
hope this helps
