Jackson is creating a water garden surrounded by a triangular patch of grass. If the pond will take up the space indicated by the circle, how many square feet of sod will he need to complete the garden (use 3.14 for and round your answer up to the next foot)? There's a diagram of a right triangle hypotenuse labeled as 10___shorter leg labeled as 6..bottom leg is labeled 8ft. Inside the triangle is a circle with a diameter of 4ft PLEASE HELP ME.
area of triangle: 1/2 * 6 * 8 = 24
area of circle: pi * 2^2 = 4pi
area of sod: 24 - 4pi = 11.43
