So the formula for the circumference of a circle is π x diameter
Since we know the the circumference already, we just divide that by π:
12π / π = 12
Now we halve the diameter to get the radius:
12 / 2 = 6
The area of a circle is π x radius²
So the area is:
·π x 6² = 36π· (or 113 not in terms of π)
Answer:
$6
Step-by-step explanation:
0.15 multiplied by 40
Using the Pythagorean theorem we can solve for the radius

-2,-7 because you go the same ammount in the opposite direction
