Find the area and circumference of the circle x 32 y 82 64 S

Find the area and circumference of the circle (x 3)2 (y 8)2 64

Solution

a)

Circumference of a circle = Pi times Diameter

(x - 3)^2 + (y - 8)^2 = 64 <-- 64 is the radius^2

so square root 64 = 8 which is the actual size of the radius

8 time by 2 = 16 which is the diameter of the circle

so 16 time by Pi = 50.26548246 <-- this is the circumference of the circle
