w Question 12 (1 point) The volume V of a tumor can be approximated by V(r) = =173 where r is the radius of the tumor, in centimeters. The rate of change of the volume at r = 1.4 cm is: 8 Note: For consistence in the calculations, round up the final number (the answer) of the calculations so if you get 2.0456 it will be 3 and if you get 2.8912 it will be 3. O a ) 4 cm 2 O b) 5 cm 2 13 O c) 6 cm 2 O d) 7 cm
