A circular plate has circumference 28.3 inches. What is the area of this plate? Use 3.14 for pi.

A =63.76512739 in^2

Step-by-step explanation:

The circumference is given by

C = 2 * pi * r

28.3 = 2* 3.14 *r

28.3 = 6.28r

Divide each side by 6.28

28.3/6.28 = 6.28r/ 6.28

4.506369427 =r

Now we need to find the area

A = pi r^2

A = 3.14 (4.506369427)^2

A =63.76512739 in^2

Area = 63.9 inches²

Step-by-step explanation:

The formula for determining the circumference of a circle is expressed as

Circumference = 2πr

Where

r represents the radius of the circle

π is a constant whose value is 3.14

From the information given,

circumference = 28.3 inches

Therefore,

28.3 = 2 × 3.14 × r

28.3 = 6.28r

r = 28.3/6.28

r = 4.51 inches

The formula for determining the area of a circle is expressed as

Area = πr²

Area = 3.14 × 4.51² = 63.9 inches²

answer: e 9, 5.75

step-by-step explanation:

step 1

find the variation ab in the x coordinate

delta x=(x2-x1)=10-> 8 units

find the variation ab  in the y coordinate 

delta y=(y2-y1)=6-> 2 units

step 2

find the coordinates point c

  x coordinate 

cx=ax+delta x*2/> cx=2+8*(2/> cx=3

  y coordinate 

cy=ay+delta y*2/> cy=4+2*(2/> cy=4.25

the coordinates of point c are (3,4.25)

step 3

find the coordinates point d

  x  coordinate 

dx=ax+delta x*4/> dx=2+8*(4/> dx=4

  y  coordinate 

dy=ay+delta y*4/> dy=4+2*(4/> dy=4.5

the coordinates of point d are (4, 4.5)

step 4

find the coordinates point e

  x  coordinate 

ex=ax+delta x*4/> ex=2+8*(6/> ex=5

  y  coordinate 

ey=ay+delta y*4/> ey=4+2*(6/> ey=4.75

the coordinates of point e are (5, 4.75)

step 5

find the coordinates point f

  x  coordinate 

fx=ax+delta x*4/> fx=2+8*(8/> fx=6

the coordinates of point g are (7,5.25)

step 7

find the coordinates point h

  x  coordinate 

hx=ax+delta x*4/> hx=2+8*(12/> hx=8

  y  coordinate
