Answer:
The area of the circle is 28662 M².
Step-by-step explanation:
Given:
Circumference of circle = 600 M.
Now, to find the area of the circle.
So, <em>to get the area we need to find the radius.</em>
By putting the formula of circumference we get the radius:
Let the radius be r.
Circumference = 2πr
(taking the value of π = 3.14.)
Dividing both sides by 6.28 we get:
Now, <em>for getting the area we put the formula:</em>
Area = πr²
So, <u><em>approximately the area of the circle = 28662 M²</em></u>.
Therefore, the area of the circle is 28662 M².

We have a transversal across parallel lines so we get the usual array of congruent and supplementary angles. We just have to figure out which is which, and the diagram, even though not to scale, makes it pretty obvious.
Angle x isn't the same as the 40° angle so it must be its supplement.
Answer: C 140°
3.
r=1.2, h=2.9, V = (1/3) πr²h
Nothing hard here, we just plug in the numbers,
V = (1/3) π (1.2)² (2.9) ≈ 4.37310
Answer: B. 4.4 cubic inches
4.
Dilation by .5 makes a similar triangle, and reflection is an isomorphism (i.e. it doesn't change the size or shape) so the answer is
Answer: B similar not congruent
5.
The corresponding interior and exterior angles of a triangle form a linear pair, so supplementary angles. x=180-110 = 70°
Answer: A 70°
Answer:
this is just math jargon... a conjugate is the same numbers but with an opposite sign.. got it?
Step-by-step explanation:
z1' ( the prime is often used for conjuates it's also used in calculus but later)
Z1' =8-i
