Answer:
Let's imagine the image of the zoo.
The diameter is basically the length of the circle.
The penguin swam the radius.
To find the radius, we need to divide the diameter by 2.
The diameter is 20 meters.
20 
2 = 10 meters.
2 x pi x 10 = 62.83185307
62.83185307/2 = 31.41592654
Answer = 31.41592654
Answer:
x = 91, y = 89, z = 31 Fourth choice
Step-by-step explanation:
x = 180 - 51 - 38 = 91
y = 180 - 91 = 89
z = 180 - 60 - 89 = 31
Answer:
A = k² - 5k - 36
Step-by-step explanation:
(k + 4)(k - 9) = k² - 9k + 4k - 36 = k² - 5k - 36
Answer:
regular polygon:
E & C
irregular polygon:
A & B
Not polygon:
D & F
Explanation:
<em>regular</em><em> polygon</em><em>:</em><em> </em>
has equal sides however the number of side and regular shape and it has equal angles between its sides. <em>"</em><em>ex"</em><em> </em><em>(</em><em>equilateral</em><em> </em><em>triangle</em><em>)</em>
as in figure C & E.
<em>Irregular</em><em> </em><em>polygon</em><em>:</em>
the opposite of regular polygon but both has a straight line all over the shape. as in figure B & A.
not a polygon:
it's may be a circle or a part of it.as in figure D & F.
The answer is e, atleast I'm pretty sure its been awhile since I've done slope.
