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

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
