Step-by-step explanation:
Hi there,
To get started, recall the area of a bound circle formula:
where r is radius of the circle. However, Juan used an approximate value of π, 3.14. So for our purposes, the formula becomes:
Juan measured the circle's <em>diameter</em>, so we can find radius from diameter first. Radius is simply twice the length of the diameter; from one circle endpoint to the center, to the endpoint across, making a straight line:
⇒
Now plug in to obtain area:
The area is 19.265 centimetres squared.
Cross-sections are the area shapes when you cut through a 3D volume; if you cut through a pipe perpendicular to where it flows, you can see it is a circle! If you cut straight through a cube, it would be a square, etc.

The correct answer is that it is 6% higher than the theoretical probability. You can find this because with 2 possible, equal outcomes, the theoretical probability is that you will get heads and tales 75 times. However, since we got heads 84 times in the experiment, we know that it is 6% more than 75.
Answer: B: 0.81 miles
Step-by-step explanation:
The find the total distance, you must look for firs the missing side. To get use the formula that is derived from the Pythagorean theorem which states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
The formula for this is: a^2 + b^2 = c^2
So let the first side or a be .19
and the second side be .28
and now we are looking for c which is the missing side
.19^2 + .28^2 = c^20.0361 + 0.784 = .1145
get the square root of .1145
√.1145 = it is approximately 0.34
get the total distance by adding three sides
= .34 + .19 + .28
= 0.81
Answer:
CED = 172°
Step-by-step explanation:
CDE = 360° - 35° - 50° - 103°
CDE = 172°
