Your grandmother buys 10 spherical grapefruits, each with a diameter of 3 3/4 inches. Your grandmother plans to juice the grapefruits and to save the peels to make candied citrus peels. She lays the peels out to dry on 9' X 13" rectangular pans. How many pans are required?

you would use (d.) the law of cosines or a^2 = b^2 + c^2 – 2bc(cos a)

, b^2 = a^2 + c^2 – 2ac(cos b), or c^2 = a^2 + b^2 - 2ab(cos c). you wouldn't use b. the law of sines as it is mostly effective when 1side and 2angles are given. a and c aren't the answer for they are the improper versions of the law of cosines. hope this is .
