The period of the pendulum is 11.11 seconds.

EXPLANATION

From the given equation,

L= 0.81t² -----------------------------------------(1)

But L= 100 feet

Substitute the value of L into equation (1)

That is;

100 = 0.81t²

Divide both-side of the equation by 0.81

[tex]\frac{\cancel{0.81}t^2}{\cancel{0.81}}=\frac{100}{0.81}[/tex]

[tex]t^2=123.45679[/tex]

Take the square root of both-side of the equation.

[tex]t\approx11.11[/tex]

T= 11.11 seconds.

Hence, the period of the pendulum is 11.11 seconds.
