Answer:

Yes you can, as the circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle, and if you have the radius you simply multiply it by 2 to find the diameter.

Please reword this question but judging this I think this means you have to know the area of a circle which is π×r*2.

If you have the circumference you divide by 2 and square it.

If you have a radius you have to just square it.

If this did not help reply back.

Hope this helps you and enlightens your day. Enjoy...

Which step is included in the graph of the function f(x)=[x-1]? (the brackets are ceiling functions symbols)

KiRa [710]

we are given

f(x)=[x=1]

where bracket means ceiling functions

we know that

Ceiling function returns the least value of the integer that is greater than or equal to the specified number

so, we can check each options

option-A:

$-4\leq x$

At x=-4:

f(x)=[-4-1] =-5

For x<-3:

Let's assume

x=-3.1

f(x)=[-3.1-1] =[-4.1]=-5

so, this interval is TRUE

option-B:

$-2\leq x$

At x=-2:

f(x)=[-2-1] =-3

For x<-1:

Let's assume

x=-1.1

f(x)=[-1.1-1] =[-2.1]=-3

so, this is FALSE
