A circle has a sector with area 33 pi and a central angle of 11/6 pi radians. What is the area of a circle?

36π

Step-by-step explanation:

The area of a circle is given as:

where r = radius of the circle

The area of a sector of a circle is given as:

where α = central angle in radians

Since is the area of a circle, A, this implies that:

A circle has a sector with area 33 pi and a central angle of 11/6 pi radians.

Therefore, the area of the circle, A, is:

The area of the circle is 36π.

Then we can conclude that the area for the circle would be

Step-by-step explanation:

For this case we know that a sector have an area of with a central angle of

We know that the total area of a cricle is and we want to find the area of the circle and we can use the following proportional rule:

From the last equation we can solve for and we got:

And replacing we got:

Then we can conclude that the area for the circle would be

answer: .75 km

step-by-step explanation:

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
