Given:

radius of the pendulum = 6 feet
arc length = 14.13 feet
time = 3 seconds

Required:

What is the angular velocity?

Solution:

To compute for the angular velocity, we can use the formula:

w = s/rt

where,

w is the angular velocity
s is the length of the arc
r is the radius of a circle or pendulum
t is the time

substituting the values,

w = 14.13 feet / 6 feet × 3 seconds

w = 0.785 per seconds

You are resurfacing your backyard pool. The pool is in the shape of a rectangular prism with a length of 20 ft, a width of 10 ft

zepelin [54]

Answer:

$440\ ft^2$

Step-by-step explanation:

we know that

The area of the backyard pool to be resurfaced is equal to the area of the base plus the area of its four lateral sides.

so

$A=B+PH$

where

B is the area of the base

P is the perimeter of the base

H is the depth of the pool

<em>Find the area of the base B</em>

$B=(L)(W)$

substitute the given values

$B=(20)(10)=200\ ft^2$

<em>Find the perimeter of the base P</em>

$P=2(L+W)$

substitute the given values

$P=2(20+10)=60\ ft$

we have

$H=4\ ft$

<em>Find the area of the backyard pool to be resurfaced</em>

$A=B+PH$

substitute the values

$A=200+60(4)$

$A=440\ ft^2$
