Acircular plate has circumference 18.2 inches. what is the area of this plate? use 3.14 for pi.

26.22in²

Step-by-step explanation:

First get the radius using the formula of a circumference.

C = 2πr = 18.2

   2(3.14)r = 18.2

   6.28r = 18.2

Divide both sides by 6.28 to get r

r = 2.89

Now get the area of a circle using the formula:

A = πr²

A = 3.14(2.89)²

A = 3.14(8.35)

A = 26.22in²

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
