In order to find the circumference, we first need to find the radius. We have the area, so we can find the radius. We set up this equation:

We begin by dividing both sides by pi.
483.76 =

Next, we take the square root of both sides to get the radius.
r = 22.
Next, we plug this into the formula for the circumference, 2 pi r

So, the circumference of this circle is 138.23 units.
Answer:
sin(x) and cos(y) are equal and have ratio of 1 : 1
First find the missing hypotenuse using Pythagoras theorem:
a² + b² = c²
12² + 5² = c²
c = √144+25
c = 13
using sine rule:


using cosine rule:


Multiplying decimals is the same as multiplying whole numbers except for the placement of the decimal point in the answer. When you multiply decimals, the decimal point is placed in the product so that the number of decimal places in the product is the sum of the decimal places in the factors.
Answer: x ≥ -4 (in words: x is greater than or equal to -4)
Step-by-step explanation:
The number line shows all values greater than -4 being shaded in, meaning that x can be any of them. In addition, the point at -4 itself is shaded in, showing that it is also a possible value for x.
Answer:
<h2>22 meters.</h2>
Step-by-step explanation:
It's important to notice that the area is circular, which is defined by

Replacing given values and solving for r, we have

But, the diameter is twice the radius, so

Therefore, the diameter is 22 meters.
