Step-by-step explanation:
Answer:
The correct answer is -
a. 4.5 inches.
b. side or arm (a)
c. (a) or 4.5, and 18
d. (d) 4.5, and 14.1428
e. 22/7 × r^2 = 15.90
Step-by-step explanation:
Given :
Radius or r = 2 ¼ inches
Solution:
a. the diameter of the circle -
d = 2r
= 2 ¼ *2
= 2.25*2
= 4.5
b. The diameter of the circle is the same length as one side or arm of the square which is
a = d = 4.5
c. The perimeter of the square
P = 4a = 4d = 4*4.5 = 18
d. Perimeter of the circle =
2πr = πd = (22/7)*4.5
= 14.1428
e. the area of the circle =
22/7 × r^2
= 15.90
Answer:
The answer to your question is: d
Step-by-step explanation:
x³ - 18
a) (x + 3)(x - 6) The polynomial given do not have the structure x² - mx +
+ c, so this option is incorrect
b) (x - 3)(x + 6) This polynomial do not have the structure x² - mx + c.
c) (x + 3) (x² - 4x + 6) The polynomial given is not a difference of cubes.
d) The polynomial is irreducible because 18 does not have a cubic root.
I believe the answer is C. Hope this helps! Also please don’t click on any unknown links that people may post because you don’t really know where they lead to or whether they are safe. Stay safe and have a nice day!
