0.000432
Step-by-step explanation:
Since we have a negative exponent 4 with a base of 10, we simply just move the decimal place 4 places to the left. When you do so, fill in your remaining zeros and you should get your answer.
Answer:
Step-by-step explanation:
Remember that
Area of Circle =

They told us that for this circle, the area is 
If you put it back into the formula for area of a circle we get:
Area of Circle =

Divide both sides by
.
144 = 
Now we want to solve for r (r = radius).
You need to square root each side


So now we know the radius,
metres
Also remember that
Diameter = 
So,
Diameter = 2 times 12 = 24 metres
X = one number
125 - x = other number
5x - 3(125 - x) = 41
==> 5x - 375 + 3x = 41
==> 8x = 416
==> x = 52, one number, and
125-52 = 73, the other number.
