<u>Area of a Circle</u>
A circle is a geometric shape where all the points on its circumference are at the same distance to a fixed point called center. The radius is the distance from the center to any point of the circumference.
The relation of the length of the circumference to the radius is an irrational number called pi (
).
Another interesting relation in a circle is the area it occupies in a 2D space. Being r the radius of the circle, the area is computed by the formula

The party hat has a radius of r= 3 inches. The area of the circular base is computed as follows


Answer:
x=3.99 it represents the amount per book
Step-by-step explanation:
3x + 1.50 = 13.47
- 1.50 on both sides
3x= 11.97
Divide 3 on both sides.
x= 3.99
Answer:
lol
Step-by-step explanation:
Given exponential expression :
.
<em>According to exponents of exponent rule, we need to distribute whole exponent over exponents of inside terms of parenthesis.</em>
We are given whole exponent 2 there.
We can apply exponents of exponent rule.
Therefore,



Therefore, 
<h3>Correct option is second option

</h3>
Hi there!
To find x, we'll need to proceed methodically. First, we'll start by finding the length of ST. The 30-60-90 relationship tells us that ST = 2. Then, we can find RT, also using the 30-60-90 relationship. RT = 4. Lastly, we can use the 45-45-90 relationship to determine that x = 4.
Hope this helps!! :)
