Perimeter of a quarter circle is 17.85 what is the quarter circles radius
givi [52]

The radius of the given circle  is 2.84 units

Step-by-step explanation:

Step 1 :

Given

The perimeter of a quarter table is 17.85

We need to find the circle's radius.

Step 2 :

The circle's perimeter is given by the formula, 2 \pi r where r represents the circle's radius

So from this we have ,

2 \pi r = 17.85

We can determine the radius by dividing the perimeter value by 2 \pi

= >  r = 17.85 divided by 2 \pi r

        = 2.84 [ taking  \pi  = \frac{22}{7}]

Step 3 :

Answer :

The radius of the given circle  is 2.84 units

Answer:

6x-4y=24

Step-by-step explanation:

From the graph, there are two intersections to be found one at (4,0) and another at (0,-6)

Now,

slope,m= y1-y2/x1-x2

=0+6/4-0

=3/2

The equation of the straight line passingt through the point (4,0) is

y-y1=m(x-x1)

or, y-0=3/2 (x-4)

or, 2y=3x-12

or, 3x-2y=12

or, 2(3x-2y)=2(12) [Multiplying both sides by 2]

or, 6x-4y=24
