QUESTION 1 The radius of a ball was measured and found to be 25 cm with a possible error in measurement of at most 0.01cm. What is the maximum error in using this value of the radius to compute the volume of the ball? Please enter your answer in decimal format with three significant digits after the decimal point. QUESTION 2 The radius of a disk is given as 15 cm with a maximum error of 0.25 cm. Use differentials to estimate the relative error in the calculated area of the disk? Please enter your answer in decimal format with three significant digits after the decimal point. QUESTION 3 The edge of a cube was found to be 30 cm with a possible error in measurement of 0.1 cm. Use the differentials to estimate percentage error when computing the surface area of the cube. Please enter your answer in decimal format with three significant digits after the decimal point
