Question 1: The volume of a sphere is given by: V = (4/3) * (pi) * (r ^ 3) Where, r: sphere radio Substituting values we have: V = (4/3) * (3.14) * ((10/2) ^ 3) V = 523.3333333 Rounding the nearest whole number we have: V = 524 m ^ 3 Answer: option 1 V = 524 m ^ 3
Question 2: The area of a sphere is given by: V = (4) * (pi) * (r ^ 2) Where, r: sphere radio Substituting values we have: V = (4) * (3.14) * ((15/2) ^ 2) V = 706.5 Rounding the nearest whole number we have: V = 706.5 yd ^ 2 Answer: V = 706.5 yd ^ 2 option 2
