3 Suppose x is a differentiable function of t and suppose that when Find g whenx = 4ify2 = 23 x2,y 2 0. Note: Check the "Student Hint" for more help with this question. (Use symbolic notation and fractions where needed.) i If each edge of a cube is increasing at the constant rate of 3 cm/s, how fast is the volume V of the cube increasing when the length x of an edge is 3 cm long? (Give your answer as a whole or exact number.) Recall: V = s3 9 If the radius of a sphere is increasing at 6 cm/s, nd the rate of change of its volume V when the radius is 3 cm. 5 ; J 5 : nun..." u I (Use decimal notation. Give your answer to two decimal places. Do not round your intermediate calculations.) Recall: V = gm3 dV dt % Ifthe radius of a sphere is increasing at 3 cm/s, nd the rate of change of its volume V when the radius is 5 cm. (Use decimal notation. Give your answer to two decimal places. Do not round your intermediate calculations.) Recall: V = gzrr
