The circumference of the circle is given by C = 2 π r

If the radius of the circle is doubled, then new radius will be r' = 2r.

And new circumference will be C' = 2·π·(2r) = 2·(2 π r) = 2·C

It is clearly visible that new circumference is twice the original circumference i.e. C' = 4 π r

A park in the shape of quadrilateral PQRS is bordered by four sidewalks. Find the measure of each
kykrilka [37]

Answer:

135°, 63°, 63°, 99°

Step-by-step explanation:

Find attached the diagram used in solving the question.

We would use formula for sum of interior angles to get each exterior angle.

From the diagram, we added additional variables to be able to solve for sum of interior angles.

Sum of angle on a straight line = 180°

a° +15z° = 180°

b° +7z° = 180°

c° +7z° = 180°

d° +11z° = 180°

Where a,b,c and d are interior angles

Sum of interior angles = 180(n-2)

n = number of sides

For quadrilateral, n= 4

a°+b°+c°+d° = 180(n-2)

180-15z +180-7z+180-7z+180-11z = 180(4-2)

720-40z = 180(2)

720 - 360 = 40z

z = 360/40

z = 9

Each exterior angle:

15z = 15×9 = 135°

7z = 7×9 = 63°

7z = 7×9 = 63°

11z = 11×9 = 99°
