Answer: 59/4 or 14 3/4

Step-by-step explanation:

151 3 /16 ÷ 10 1 /4

Find the area of the largest trapezoid that can be inscribed in a circle of radius 1 and whose base is a diameter of the circle.

ki77a [65]

<span>Answer:
let x = shortest base of the trapezoid
A = h (x/2 + r) = âš(rÂ˛ - (x/2)Â˛) (r + x/2)
= âš(1 - (x/2)Â˛) (1 + x/2) .... if r = 1
dA/dx = (2 - x - xÂ˛) / (2âš(4 - xÂ˛))
= 0 at x = 1 .... which is a relative maximum because dÂ˛A/dxÂ˛ < 0
A = (3/4) âš3</span>
