To find the total surface area of the remaining solid after hollowing out a conical cavity from a solid cylinder, we will follow these steps: ### Step 1: Determine the radius and height of the cylinder - Given the diameter of the cylinder is 1.4 cm, we can find the radius (r) by dividing the diameter by 2. \[ r = \frac{1.4}{2} = 0.7 \text{ cm} \] ...
