The diameter of a circle is 8 miles. What is the radius?

4 miles

Step-by-step explanation:

The diameter is twice the radius, or

d=2r

We know the diameter is 8, so we can substitute that in for d

8=2r

Since we want to solve for, r, we need to get r by itself. To do that, divide both sides by 2

8/2=2r/r

4=r

So, the radius is 4 miles

∞ this is your sign

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
