100 * pi = pi * r^2
Pi cancels on both sides of the equation
So... 100= r^2
= radius is 10
Answer:
simplify: 14/40
not simplify: 7/20
I don't know if it's right but i'm trying to help :)
This equation is in slope-intercept form of y = mx + b form.
The m represented by the coefficient of the x term
represents the slope and b represents the y-intercept.
So our y-intercept is -4 and we can write this as the ordered pair (0, -4).
Normally if you have the things legnth
and height, you and another thing, then normally the other thing
would be area and you would have 2 given and 1 to solve.
Probably your question is
legnth=?
Height=1.0
decimal part is confusing, I am
guessing that you mean area
area=0.8
so use formula
height times legnth=0.8
1.0 times blank=0.8
divide both sides by 1.0
blank=0.8/1=0.8
blank=0.8
legnth=0.8
