What is the approximate circumference of the circle? Use π ≈ 3.14. Circle A with radius 18 feet. 21.1 feet 36 feet 56.5 feet 113
Ilia_Sergeevich [38]
C= 2*pi*r
pi= approx. 3.14
So
The first one with the radius being 18 would be approximately 113.04
BECAUSE 18 * 2 = 36
36*3.14= 113.04
DO THE SAME PROCESS with the other values you were given...

Also if they give you the diameter the formula is C= d*pi
that formula is the same as c=2*pi*r  ..... Use either... just remember when they give you the radius.... the radius is half of the diameter... so take the radius times 2 and times that by pi 
When it asked for an approximation use 3.14 for pi.
I'm sure you can do the rest by yourself. I hope this helped!

A(1)= -13 <br><br> a(n)= a(n-1)+4 <br><br> Find the 2nd term in the sequence
eimsori [14]

The second term of the arithmetic sequence is:

a₂= -9

<h3>How to find the second term in the sequence?</h3>

Here we have an arithmetic sequence, such the the recursive formula is:

aₙ = aₙ₋₁ + 4

So to get each term, we need to add 4 to the previous one.

We know that the first term is:

a₁ = -13

Then the second term will be:

a₂ = a₁ + 4 = -13 + 4 = -9

16. Find the final balance in an account with $730 invested at 3% annual simple interest for 4 years. (1 point) $735.48 $87.60 $
podryga [215]

Answer:

$817.60

Step-by-step explanation:

Simple interest has the formula:

Simple Interest = Principal * rate * time

here,

Principal amount is $730

The rate of interest is 3%, which is 3/100 = 0.03

The time length in years is given as 4

We find the interest amount first:

SI = P * r * t

SI = 730 * 0.03 * 4

SI = 87.6

We are asked to find FINAL BALANCE, which is PRINCIPAL + INTEREST

So,

Final Balance = 730 + 87.6 = $817.60
