Answer:
Distance around the circle is perimeter.
Perimeter = radius * 2 * π = diameter * π
Step-by-step explanation:
π = constant =3.14
You can do:
6x7000 then
6x300 then
6x80 then
6x1 then
you add all the product.
the answer 4,4286
Answer: it will trave 56.89 meters before coming to rest.
Step-by-step explanation:
This is a geometric progression since the distance travelled (height) by the ball is reducing by a constant ratio, r. Since the number of times that the ball will bounce is infinite, then we would apply the formula for determining the sum of the terms in a geometric progression to infinity which is expressed as
S = a/(1 - r)
where
S = sum of the distance travelled by the ball
a = initial distance or height of the ball
r = common ratio
From the information given,
a = 128/9
r = (32/3)/(128/9) = 0.75
Therefore,
S = (128/9)/(1 - 0.75) = 56.89 meters
$4/3=$1.33 per pound.
$9/8 = $1.13 per pound.
The second one is cheaper.
