Your answer would be 4, because the equation for the circumference of a circle is π × diameter, so if you have 4 × π as the circumference, then 4 is the diameter.
I hope this helps!
Answer:
(x-10)²+(y+9)²= 324.
Step-by-step explanation:
For this question, you will need to substitute these values into the equation of a circle:
(x-h)²+(y-k)²= r²
'h and k' represent the center points, and 'r' represents the radius.
This will result in:
(x-10)²+(y+9)²=324.
Answer:
4x+8=-24 and
4x=-32
Step-by-step explanation:
2/3(6x+12)=-24
or,12x+24=-72
or,x=-72-24/12
•°•x=-8
4x+8=-24
or,x=-24-8/4
•°•x=-8
4x=-32
or,x=-32/4
•°•x=-8
4 / 1 = 1 / x....4 miles to 1 hr = 1 miles = x hrs
cross multiply
4x = 1
x = 1/4.....it would take 1/4 of an hr (or 15 minutes) to walk 1 mile
