the ratio of the length of an arc of the circle to the circumference of the circle is 3:7, if the diameter of the circle is 14cm

konstantin123 [22]

The perimeter and area of this minor circle are equal to 32.857 units and 88.345 units² respectively.

<h3>How to calculate the perimeter of the minor circle?</h3>

First of all, we would determine the circumference of this circle by using this formula:

C = πD

C = 22/7 × 14

C = 44 units.

For the length of an arc of the circle:

Arc length/Circumference = 3/7

Arc length = 3/7 × C

Arc length = 3/7 × 44

Arc length = 18.857 units.

Now, we can calculate the perimeter:

Perimeter = 2r + arc length

Perimeter = 2(14/2) + 18.857

Perimeter = 14 + 18.857

Perimeter = 32.857 units.

<h3>The area of the minor circle.</h3>

Mathematically, the area of a minor circle is given by this formula:

Area = θr²/2

But, we would have to find the angle in radians:

18.857/32.857 = θ/360

θ = 3.6059 radians.

Substituting the given parameters into the formula, we have;

Area = (3.6059 × 7²)/2

Area = 88.345 units².

In △ RTV , X is the centroid and RU = 18. Find RX and XU. Enter your answers as numbers.

lapo4ka [179]

Answer:

RX = 12 and XU = 6

Step-by-step explanation:

Given : In ΔTRV , TW ,RU and VS are the medians .

X is the centroid

To Find : RX and XU

Solution:

Since we know that the centroid divides each median in a ratio of 2:1.

Since X is the centroid so RX : XU = 2:1

So, let RX = 2x and XU = x

And we are given that RU = 18

⇒RX +XU=18

⇒2x+x=18

⇒3x=18

⇒ $x=\frac{18}{3}$

⇒ $x=6$

Thus, RX = 2x = 2*6 =12

XU = x =6

Hence length of RX = 12 and XU = 6
