![C = \pi d](https://tex.z-dn.net/?f=C%20%3D%20%5Cpi%20d)
Step-by-step explanation:
Given
A circular ring
Required
The length
Let
the radius of the ring
The length is calculated by calculating the circumference of the ring.
This is calculated using:
![C = 2\pi r](https://tex.z-dn.net/?f=C%20%3D%202%5Cpi%20r)
or
![C = \pi d](https://tex.z-dn.net/?f=C%20%3D%20%5Cpi%20d)
Where
diameter
and ![d = 2r](https://tex.z-dn.net/?f=d%20%3D%202r)
Answer:
![\$164.5](https://tex.z-dn.net/?f=%5C%24164.5)
Step-by-step explanation:
Bonnie deposits $70.00 into a new savings account.
The account earns 45% simple interest per year.
She neither added or removed from the savings account for 3 years.
We know that,
![i=\dfrac{P\cdot r\cdot r}{100}](https://tex.z-dn.net/?f=i%3D%5Cdfrac%7BP%5Ccdot%20r%5Ccdot%20r%7D%7B100%7D)
here,
i = interest,
P = principal = $70,
r = rate of interest = 45%,
t = time = 3 years,
Putting the values,
![i=\dfrac{70\cdot 45\cdot 3}{100}=\$94.5](https://tex.z-dn.net/?f=i%3D%5Cdfrac%7B70%5Ccdot%2045%5Ccdot%203%7D%7B100%7D%3D%5C%2494.5)
So the total amount will be,
![=\text{Principal}+\text{Interest}](https://tex.z-dn.net/?f=%3D%5Ctext%7BPrincipal%7D%2B%5Ctext%7BInterest%7D)
![=70+94.5](https://tex.z-dn.net/?f=%3D70%2B94.5)
![=\$164.5](https://tex.z-dn.net/?f=%3D%5C%24164.5)
Find a ∩ b if a = {2, 5, 8, 11, 14} and b = {1, 3, 5, 7}. {1, 2, 3, 5, 7, 8, 11, 14} {5}
Maslowich
The intersection of given set a and b is a∩b = {5}.
According to the given question.
We have two sets a and b.
a = {2, 5, 8, 11, 14}
And, b = {1, 3, 5, 7}
As, we know that "the intersection of two sets A and B is the set of all those elements which are common to both A and B. Symbolically, we can represent the intersection of A and B as A ∩ B".
Since, only the element which is common to set a and set b is 5.
Thereofore, the intersection of given set a and b is given by
a∩b = {5}
