Answer:
Step-by-step explanation:
The first one is A, please tell me if you would like an explanation.
The second one is D. The point where the lines intersect each other.
<span>The pair of integers that I chose are:
(a) sum is –3
5 + (-8) = -3
(b) difference is –5
2 - 7 = -5
(c) difference is 2
14 -12 = 2
(d) sum is 0
2 - 2 = 0</span>
What do you mean I’m confused
Radius is equal to 1/2 the diameter. The radius is 14 (28/2=14)
With your formula:
c=2*14
c=28
HOWEVER I believe you meant
c=2(pi)r
In which
c=2(pi)14
c=28(pi)
In this instance for pi we can use 3.14 since we will be rounding anyway, so
c=28*3.14
c=87.92
Rounded to be
c=88
Note:
If we didn’t round pi out to 3.14 we would have gotten 87.964594...
43.8444444444 --> and it keeps going on because it's a repeating decimal.
if u dont feel like writing a billion 4s, then simply write one 4 and add a dot above it, that shows that it's a repeating decimal.
or, instead of that you can round to 43.84
hope this helps and have a great day! :D
