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;
