2) You need pi because of the circumference to calculate how long the perimeter is.
3) 113.1 = Area
4) You would need to adjust how many number places of pi you use for how huge the number you need to calculate for.
5) To write an exact number for an irrational expression you need to calculate then round to the nearest hundredths after you get the number for either radius, diameter, or area. To find the approximate value you only use the minimum numbers such as 3.14 instead of 3.14159...
6) How this helped me better estimate the value of an irrational expression is by using more numbers for every extra number place the circle has in the diameter.
8ft by 12ft and 10ft by10ft
Answer:
Yes
Step-by-step explanation:
Substituting in x = -7, we get y = 6(-7) = -42, which is the same as the y coordinate of the given point.
Answer:
<h2>a. AB = 24</h2>
Step-by-step explanation:
We have a triangle 45° - 45° - 90°.
Sides are in the ratio 1 : 1 : √2 (<em>look at the picture</em>).
If then

Interesting question! Let's first break this up:
We can now simplify this by crossing out numbers that appear in both denominator and numerator. This becomes
Therefore, the answer is 12
