Refer to the profile drawing for a hatch on a boat. If the height is 9 inches and the width is 36 inches, what is the radius of the hatch top, to the nearest tenth inch? height width hint: look for that right triangle, with one corner at the center of the circle, and the other corners at the edges of the hatch. Since 2 sides of the triangle are the same (radius of the circle), it is an isosceles triangle. Split it in half to get a right triangle. Find numbers or equations for the lengths of 2 sides, plug them into the pythagorean theorum, and solve for r.
