For this case we have that by definition, the volume of a cone is given by:
Where:
r: It is the radius of the cone
h: It is the height of the cone
According to the statement data we have:
Substituting in the formula:
We cleared the radius:
We choose the positive value:
We round and we have that the radius of the cone is:

The total surface area of the solid object is 2660.925 square cm the answer is 2660.925 square cm.
<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.
