<h3>What is a cylinder?</h3>In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.
We know the volume of the cylinder is given by:
The surface area of the
= surface area of half sphere + surface area of the cylinder - surface area
of one circular base
The radius r = (64-50)/2 = 7 cm
= (1/2)[4π(7)²] + 2π(7)(50) + 2π(7)² - π(7)²
= (1/2)[615.75] + 2506.99 - 153.94
= 307.875 + 2506.99 - 153.94
= 2660.925 square cm
Thus, the total surface area of the solid object is 2660.925 square cm the answer is 2660.925 square cm.
