Using the greatest common factor for the terms, how can you write 60 + 44 as a product?
a) 2(30 + 22)
b) 4(15 + 11)
c) 6(10 + 7)
d) 12(5 + 3)

You factor out 4 from each, so (60+44) becomes 4(15+11), or B

-- The point (3, 0) is on the circle.

-- So the distance to it from the center of the circle
must be the radius of the circle.

-- The center of THIS circle is at the origin.

-- The distance from the origin to (3, 0) is 3 .

-- The radius of this circle is 3 .

-- The area of any circle is (pi) (radius of the circle)²

-- The area of THIS circle is (pi) (3)² = 9 pi = 28.27 (rounded)
