Answer:

Step-by-step explanation:

The perimeter P of a rectangle is calculated as

P = 2l + 2w ( l is the length and w the width ) , then

2l + 2(9) = 5364

2l + 18 = 5364 ( subtract 18 from both sides )

2l = 5346 ( divide both sides by 2 )

l = 2673

Then

A = lw = 2673 × 9 = 24057 m² → D

Quadrilateral ABCD is inscribed in this circle.

miskamm [114]

The measure of angle A is 65°

Explanation:

Given that ABCD is a quadrilateral inscribed in a circle.

The measure of angle A is $\angle A=(2x+1)^{\circ}$

The measure of angle B is $\angle B=148^{\circ}$

The measure of angle D is $\angle D=x^{\circ}$

We need to determine the measure of angle A.

Since, we know that the angles B and D are opposite angles and the opposite angles of a quadrilateral add up to 180°

Thus, we have,

$\angle B+\angle D=180^{\circ}$

Substituting the values, we have,

$148^{\circ}+x=180^{\circ}$

$x=32^{\circ}$

Thus, the value of x is 32°

Substituting the value of x in the measure of angle A, we get,

$\angle A=(2x+1)^{\circ}$

$\angle A=(2(32)+1)^{\circ}$

$\angle A=(64+1)^{\circ}$

$\angle A=65^{\circ}$

Thus, the measure of angle A is 65°

Someone help I don't know what the diameter or radius is

Elenna [48]

<h3>Answer:</h3>

52.38 inch² & 261.90 inch²

<h3>Step-by-step explanation:</h3>

Here we need to find the area of the sector . So according to formula we know the area of sector as ,

$\boxed {\sf Area_{(sector)}= \dfrac{\theta}{360}\times \pi r^2 }$

Here we can see that the central angle subtended by the arc is 60° and the radius of the circle is 10 inches . So the required area would be ,

=> Area = ∅/ 360° × π r²

=> Area = 60°/360° × 22/7 × (10in.)²

=> Area = 1/6 * 22/7 * 100 in²

=> Area = 52 .380 in²

<h3>★ Hence the area of the red sector is 52.38 inch².</h3>

_________________________________

Now let's find out the area of blue sector .The angle subtended by the arc will be (360-60)°=300° .

=> Area = 300/360 × 22/7 × 100 in²

=> Area = 261. 90 in²

<h3>★ Hence the area of blue sector is 261.90 inch².</h3>

$\boxed{\red{\sf Area _{(red \ sector )} = 52.38 in^2 }}$

$\boxed{\blue{\sf Area _{(blue \ sector )} = 261.90 in^2 }}$
