Answer:
130.43 cm³
Step-by-step explanation:
To find the difference between the volumes of the balls, we must first find the volumes of the balls. To find the volume of each ball, we must first determine their shape. We understand that both balls are spherical.
The volume V of a sphere wit radius r is given as
V = 4/3 πr³
where r is the result when the diameter of the sphere is divided by 2.
Hence the radius of the Golf ball
= 4.3cm/2
= 2.15cm
radius of the tennis ball
= 6.9cm/2
= 3.45cm
The difference between the volumes of the two balls
= 4/3 π (3.45³ - 2.15³)
= 130.43 cm³
Answer:
w=108
Step-by-step explanation:
Using the formula
P=2(l+w)
Solving for w
w=P
/2﹣l = 240
/2﹣12 = 108
This scenario is representing an exponential decay function.
Each time you are removing half, which will be the same as divided by two.
1, 1/2 1/4, 1/8, 1/16. You can see in the denominator the powers being applied. The values are decreasing which is why it is a decay.
Answer:
54
Step-by-step explanation:
0.54 repeating is 0.545454 and so on. If you subtract that from 0.54 repeating you get 54.
We are given chains
For Gold:
we are given length in yard
we can simplify it
In feet:
we can change in feet
we know that
1 yard =3 feet
In inch:
we know that
1 feet =12inch
For Silver:
we are given length in feet
so,
In feet:
In yard:
so, we can change feet into yard
In inch:
we know that
1feet =12 in
so, we can change feet into in
For bronze:
we are given length in in
In inch:
In feet:
we know that
so, we get
In yard:
we know that
So,
largest chain is silver
smallest chain is gold
In yard:
Largest chain is
Smallest chain is
In feet:
Largest chain is
smallest chain is
In inches:
Largest chain is
Smallest chain is
