Answer:

The length of swing is 7.8 feet.

Step-by-step explanation:

Given: T=2\pi\sqrt{\dfrac{L}{32}}

We need to find L for T=3.1 seconds

We will substitute T=3.1 sec into formula and solve for L

3.1=2\pi\sqrt{\dfrac{L}{32}}

Divide by 2π both sides

0.4934=\sqrt{\dfrac{L}{32}}

Squaring both sides

0.2434=\dfrac{L}{32}

Multiply both sides by 32

L=7.789\approx 7.8

Hence, The length of swing is 7.8 feet.
