Since the bottom shape is a semi-circle, the 3yd is the radius making the triangle's area 7 x 3 / 2 = 10.5
The semi-circle's area is
/2 = 14.14
Combined, you get an area of 10.5 + 14.14 = 24.64
The semi-circle's area is
Combined, you get an area of 10.5 + 14.14 = 24.64
By the binomial theorem,
I assume you meant to say "independent", not "indecent", meaning we're looking for the constant term in the expansion. This happens for k such that
12 - 3k = 0 ===> 3k = 12 ===> k = 4
which corresponds to the constant coefficient
