Draw two lines from center to the end of the base. Now these two line reprent the radius.

Now you have an isoceles triangle with hypoteneus as the base = 12 ft.

Since two other sides (radii) are equal, you get radius = 12/sqrt2.

Now calculate the circuference and multiply this will 3/4 which gives you 9 * pi * sqrt2.

ramesh u should say that the angle subtended at the center is 90 sinnce 1/4 *360=90 then go ahead to solve

Thanks both for your response.

Yes, that is a good point. I was at first wondering why we can determine the triangle 1:1:sqart2 but then I realize the it's 90degree triangle.

i think the radius is 6 * sqrt2

only then you get 9* pi * sqrt 2

no?
