Answer:
In brief, apply the pythagorean theorem to show that the distance between the point and the origin is
.
Step-by-step explanation:
The pythagorean theorem can give the distance between two points on a plane if their coordinates are known.
A point is on a circle if its distance from the center of the circle is the same as the radius of the circle.
On a cartesian plane, the unit circle is a circle
- centered at the origin
- with radius
.
Therefore, to show that the point is on the unit circle, show that the distance between
and
equals to
.
What's the distance between and
?
.
By the pythagorean theorem, the distance between and the center of the unit circle,
, is the same as the radius of the unit circle,
. As a result, the point
is on the unit circle.
Answer:
The answer is 9.4 cm.
Step-by-step explanation:
To solve for the circumference of the circle, use the circumference formula, which is C = 2
.
Next, in the problem, the circle has a diameter measure but no radius measure. To find the radius of this circle, divide the diameter (3 cm) by 2, and it will equal 1.5 cm. The radius is being divided by 2 because the radius of any circle is equal to half the diameter of the circle.
Then, plug in the information given from the problem into the formula, and the formula will look like C = (2) () (1.5 cm).
Finally, solve the equation, and the answer is 9.4 cm.

<u>Part A:</u>
According to a life cycle analysis of the U.S. food system conducted by the University of Michigan, the U.S. consumes 13.9 quads of mostly fossil fuel energy to produce 1.75 quads of food energy annually. A quad is a unit of energy equal to 1 quadrillion (10¹⁵) British thermal units (BTUs). One quad is equal to the energy of 183 million barrels of petroleum.
