-- The area of any circle is  (pi) times (the circle's radius)².

If the radius is 6.8 feet, then the area is (pi) x (6.8)² = 145.27 square feet (rounded)


-- The circumference of any circle is (2 pi) x (the circle's radius).

If the radius is 6.8 feet, then the circumference is (2pi) x (6.8)= 42.73 feet (rounded)

in order to find the ares you do
a= 3.14 times r squared 
so 3.14 x 6.8 ²
 
yeppy i think thats how you do it
