The formula is d=C/π.
The diameter is 2 times the radius
The formula for the circumference using the radius is 2πr.
in order to do this backwards, we would have to do 16÷2÷π, but we're not looking for the radius.
Therefore, we take out the ÷2 part, which would be 16÷π
16 is the circumference
16÷π=d
d=C÷π
Step-by-step explanation:
normally, if we have the gradient (or slope of inclination or change rate) and a point, we start using the point-slope form :
y - y1 = a(x - x1)
with (x1, y1) being a point on the line, and a being the slope of gradient (or ... however you want to call it).
y - 1 = 2(x - 2) = 2x - 4
y + 3 = 2x
2x - y = 3
Answer:
Option C) G.
Step-by-step explanation:
Verify each expression
case E) we have

Any number plus zero equals the original number (Identity property of addition)
-----> is a decimal number
case F) we have

Any number plus zero equals the original number (Identity property of addition)
-----> is a decimal number
case G) we have

Any number plus zero equals the original number (Identity property of addition)
-----> is an integer
case H) we have

division by zero is undefined
Its pythagoras I think ^^; so 9^2 + 4.5^2 = 101.25 then square root it to get 10.0623059 just in future do a^2 + b^2 = c^2 (adjacent squared plus opposite squared gives you the longest side which is the hypotenuse squared) I hope that helps! ^^;
