The circumference and area of the circle with equation ( x − 9 ) 2 + ( y − 3 ) 2 = 64 are, respectively, 16π and 64π. This is computed using formulas for the circumference (2πr) and area (πr²) with the given radius r=8.
Given equation: ( x − 9 ) 2 + ( y − 3 ) 2 = 64
Step 1: Recognize that the equation is in the form ( x − h ) 2 + ( y − k ) 2 = r 2 , where (h,k) is the center of the circle and r is the radius. So, the center of the circle is (9, 3) and the radius is 8.
Step 2: Circumference: C = 2πr = 2π(8) = 16π units
Step 3: Area: A = π r 2 = π 8 2 = 64π square units
