T varies directly as the square of L. If T=72, then L=3.​

Sagot :

Answer:

k = 8

Step-by-step explanation:

[tex]\rm T = kL^2[/tex]

Given that T = 72 when L = 3

[tex]\implies \rm 72 = k(3^2)[/tex]

[tex]\implies \rm k = \frac{72}{3^2}[/tex]

[tex]\implies \rm k = \frac{72}{9}[/tex]

[tex]\implies \boxed{\rm k = 8}[/tex]
