Answer:

Step-by-step explanation:
Given
Shape: Right Circular cone
Height, h = 12.5 cm
Base circumference, C = 5.8cm
Required:
Calculate Volume
The volume of a cone is calculated as thus;
Volume, 
Where V, r and h represent the volume, the radius and the height of the cone respectively
But first we need to calculate the radius of the cone.
Using formula of circumference.

We have C to be 5.8cm
By substituting this value;

Divide through by 



Now, we can calculate the volume of the cone
By substituting
and h = 12.5 cm;
becomes



Take
as 3.14


---- Approximated
Hence, the volume of the cone is; 
2x-4=6
2x=6+4=10
x=5
for the inequality, however:
