Answer 1

Answer:

28.26 unit^2

Step-by-step explanation:

The circumference is given by

C = 2 * pi *r

18.84 = 2 * 3.14 * r

18.84 = 6.28 r

Divide each side by 6.28

18.84 /6.28= 6.28 r/6.28

3 = r

The area of a circle is given by

A = pi r^2

A =3.14 * 3^2

   = 28.26 unit^2

Answer 2

Answer:

28.26 units^2

Step-by-step explanation:

Solution,

Circumference of circle= 18.84 units

Finding the radius,

Circumference of circle= 18.84

or,

$2\pi \: r = 18.84$

or, 2 * 3.14 * r = 18.84

or, 6.28 r = 18.84

or, r= 18.84/6.28

r = 3 units

We have,

Radius= 3 units

Finding the area of circle:

$\pi \: {r}^{2}$

plugging the value of radius(r)

= 3.14 * (3)^2

= 3.14 * 9

= 28.26 units^2

hope this helps...
