The volume of a cone is 88π cubic feet. its height is 8 feet. fatima is finding the radius of the cone. her work is shown below. step 1: 88π = 1/3 πr² (8) step 2: 88π = 8/3 πr² step 3: 8/3 (88) = r² step 4: 234.7 = r² step 5: 15.3 =r what is fatima's error? - in step 4, fatima did not find the correct value of 8/3 (88). - in step 2, fatima should not have multiplied 1/3 and 8. - in step 3, fatima did not multiply 88 by the reciprocal of 8/3 - in step 1, fatima did not substitute the correct value for the height in the formula.
