Area=pi times radius^2 so
if area=4pi=pi times r^2
4 times pi=r^2 times pi
divide both sdies by pi
4=r^2
square root
2=radius since legnth cannot be negative
radius=1/2 diamters
2 radius=diameter
2(2)=diameter=4
diameter=4
140 / 100 * X = 56
X = 56 * 100 / 140 = 5600 / 140 = 40
I can't think of what the form is called, but the slope is in that equation.
y=mx+b
m is the slope and in that equation, m=-4/3
Answer:
the coefficient is 12
Step-by-step:a numerical or constant quantity placed before and multiplying the variable in an algebraic expression explanation:
Answer:
The length is 7.2 feet.
Step-by-step explanation:
It is a ratio of 10:18. Therefore you can simplify the ratio to 18/10 or 1.8. This then becomes 4 (width) times 1.8, or 7.2 feet. :)
