the circumference of the circle is 2 * 3.14 * 5 = 31.4 units the length of the arc of the sector = 14 = 14/31.4 as a fraction of the circumference. the area of the whole circle is 3.14 * 5^2 = 78.5 sq units

so the area of the sector = (14/31.4) * 78.5 = 35 sq units which isn't one of the options (??)
