Where L is the length, in feet, of the pendulum, and π is approximately 22 7 . How long must the pendulum be if one complete cyc
Dima020 [189]

Answer:

Length L = 51.88 feet

Step-by-step explanation:

From the given information,

The length of the pendulum can be determined by using the Formula for the period T which  is the time of one full oscillation of a simple pendulum.

T = 2 \pi \sqrt {\dfrac{L}{g}}

where;

T = period of the time of one full oscillation = 8 seconds

L = length in feet

g = acceleration due to gravity in  feet = 32 ft/s²

π = 22/7

8 = 2 \times \dfrac{22}{7} \times  \sqrt {\dfrac{L}{32}}

8 = 6.2857 \times  \sqrt {\dfrac{L}{32}}

\dfrac{8}{6.2857} =\sqrt {\dfrac{L}{32}}

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

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

1.273 \times { \sqrt {32}}}= {\sqrt L}

7.2012= {\sqrt L}

L = 7.2012²

L = 51.88 feet

How do you find the perimeter of an equilateral triangle when given area​
GrogVix [38]

Step-by-step explanation:

To find perimeter, you need to add all the sides of the shape.

The area of a traingle is 1/2 bh.

You must find the "b" in order to find the perimeter.

Example:

A triangle has an area of 18 cm^2.

Therefore, the triangle has a 6 cm base and 6 cm height.

Then multiply the base by three to get 18 cm. That is your perimeter.
