Answer:
82
Step-by-step explanation:
1071,79 = (1/2) × (4/3) πr³
1071,79 = (2/3) × 3,14 × r³
1071,79 = 2,093333 × r³
512 = r³
8³ = r³
8 = r

Answer:

Step-by-step explanation:
The equation of the given line:

This equation is in the form
. Therefore, 1/3 is the slope.
To find a perpendicular line, take the opposite reciprocal of the slope (-1/old slope). Therefore, the slope of the perpendicular line is -3.
The equation of the perpendicular line:
