<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:
Technology can be both negative and positive when it comes to modified crops. It can be positive because it allows us to have more crops and resist pests and disease. It can be negative because it may cause deformities or health risks.
I really hope that helps you.
Answer:
0.04746
Step-by-step explanation:
To answer this one needs to find the area under the standard normal curve to the left of 5 minutes when the mean is 4 minutes and the std. dev. is 0.6 minutes. Either use a table of z-scores or a calculator with probability distribution functions.
In this case I will use my old Texas Instruments TI-83 calculator. I select the normalcdf( function and type in the following arguments: :
normalcdf(-100, 5, 4, 0.6). The result is 0.952. This is the area under the curve to the left of x = 5. But we are interested in finding the probability that a conversation lasts longer than 5 minutes. To find this, subtract 0.952 from 1.000: 0.048. This is the area under the curve to the RIGHT of x = 5.
This 0.048 is closest to the first answer choice: 0.04746.
Answer:
She should leave a total of $78.
Step-by-step explanation:
To find this, we first need to find the tip amount. We can do this by multiplying the total by the tip percentage.
$65 * 20% = $13
Now that we have that, we need to add it to the cost.
$65 + $13 = $78
So, We Know That The Figure Shown Is A Square. So, We Need To Find The Area:
70*70 = 4900.
So, We Have:
490 - (Area Of The Triangle) = A
So, Lets Find The Area Of The Triangle.
(35*70)/2
Well, 35*70 = 2450.
So:
2450/2 = 1225.
Now, Do:
4900 - 1225 = A
4900 - 1225 = 3675
So:
3675cm² = A
