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

T is directly proportional to M.

zaharov [31]

By proportionality, for any number $a$ , if T is multiplied by $a$ then the same goes for M.

a) M has been multiplied by $\dfrac{3}4$ hence $T=20\cdot\dfrac{3}4=5\cdot3=15$

$\boxed{T=15}$

b) T has been divided by $2$ hence $M=\dfrac{4}2$

$\boxed{M=2}$
