Area of a circle with a circumference of 18.84

podryga [215]

Answer:

The area of a circle with a circumference of 18.84 is 28.26 units²

Step-by-step explanation:

Given:

Circumference = 18.84

Let R be the Radius of a Circle

pi = 3.14

To Find:

Area of Circle = ?

Solution:

We Know that,

$Circumference = 2\pi Radius$

Substituting the values we get the radius

$18.84=2\times 3.14\times Radius\\\\18.84 = 6.28\times Radius\\\\\therefore Radius =\frac{18.84}{6.28} \\\\\therefore Radius = 3\ unit\\$

Now Formula for calculating Area of Circle is given as

$\textrm{Area of Circle} =\pi (Radius)^{2}$

Substituting the Radius we get

$\textrm{Area of Circle} =3.14\times 3^{2}\\\\\textrm{Area of Circle} =28.26\ units^{2}$

The area of a circle with a circumference of 18.84 is 28.26 units²

Find the value of x. Please help.!!<br> Need to show work.

EastWind [94]

Answer:

(x-54)° + 2x° + 99° = 360

=> x + 2x + 99 – 54 = 360

=> 3x + 45 = 360

=> 3x = 360 – 45

=> x = 315/3

=> x = 105

The value of x is 105
