Heya
______________________________
Variation constant = ?
V = k × r² × h .... Equation ( i )
Where V is volume , r is radius and h is height.
Volume of cone = 1/3 × 3.14( 36 ×8 )
=>
V =301.44cm³
=>
301.44cm³ = k × 36cm² × 8cm
=>
k = 301.44cm³/ 288cm³
=>
k = 1.465

How do you get Area, when you divide volume by height
Please explain
I don't know, answer is not given in textbook
