Step-by-step explanation:</h3>
<u>Given:</u>
To find the area of the rug, we need to use the formula "πr² or π(D/2)²"
<u>Where:</u>
Since we do not have the radius, we need to substitute the diameter in the formula "π(D/2)²" to determine the area of the rug.

Substituting "22/7" as π:

⇒
When finding the area of ANY shape, do not forget to include the units.
⇒
The size of the triangle is 55 degrees.
The answer is 94.5x because you have to multiply 2.1 times 4.5
Answer:
Whats the X given for this problem? ex.... X = 6 and the problem is:
2x (>) or (<) or = to 13
substitute ( x = 6 ) in 2x and you get 12 is < 13.
I'll use my own formula (similar to yours tho)
A=future amount
p=invested
r=rate in decimal
n=number of times per year compounded
t=time in years
so
when will A=2P
subsitute 2P for A
also quarterly means 4 times a year or n=4
and 12%=0.12=r
so
divide both sides by P
simplify
take the ln of both sides
divide both sides by 4ln(1.03)
use calculator
5.86244=t
