4 is D
I can figure out 5, Im kinda bad at plotting.
Answer:
The answer is that last one.
Step-by-step explanation:
Yes ur right this one is right good job
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
