Consider circle H with a 6 centimeter radius. If the length of minor arc ST is
alexandr402 [8]
Given that the circle radius of 6 cm and a minor arc ST = 11pi/2. the measure of the angle rst can be solve using the formula s = ra
where s is the lenght of the minor arc
r is the radius of the circle 
and a is the measure of the angle in radians
s = ra
a = s/r
a = (11pi/2) / 6
a = 11pi/12 
or
a = 165 degrees is the measure of angle RST

how to calculate cube root without using prime factorization? and how to calculate ³√60? or something else that has a decimal re
Marat540 [252]

The cube root of 60 is 3.87 approximately.

Step by step solution:

We can calculate the cube root by Halley's method:

The  formula is \sqrt[3]{a} = x ((x^{3}  + 2a)/(2x^{3}  + a))

where,

a = number whose cube root is being calculated

x = integer guess of its cube root.

Here a = 60,

Suppose x as 3

[∵ 3³ = 27 and 27 is the nearest perfect cube that is less than 60]

⇒ x = 3

Therefore,

∛60 = 3 (3³ + 2 × 60)/(2 × 3³ + 60)) = 3.87

⇒ ∛60 ≈ 3.87

Therefore, the cube root of 60 is 3.87 approximately.

Here ,  ∛60 is irrational because it cannot be expressed in the form of p/q where q ≠ 0.

Therefore, the value of the cube root of 60 is an irrational number.

Two sides of a triangle are exactly the Same length. The length of the third side is four cm shorter than the two equal sides. F
liubo4ka [24]

Answer:

15 cm, 15 cm, 11 cm

Step-by-step explanation:

let the equal sides be x then the third side is x - 4

The perimeter is the sum of the 3 sides and is 41 cm , then

x + x + x - 4 = 41

3x - 4 = 41 ( add 4 to both sides )

3x = 45 ( divide both sides by 3 )

x = 15

x - 4 = 15 - 4 = 11

The sides are 15 cm, 15 cm, 11 cm

Here is a pyramid with a base that is a pentagon with all sides the same length
Eva8 [605]

The shape of the cross section formed from slicing the pyramid is called; a triangle

<h3>What is the Pyramid's Cross Section? </h3>

We are told that it is a pyramid with a base that is a pentagon with all sides the same length.

Now, the Pyramid's ap-ex is usually constructed by isosceles triangles. Thus, when they are sliced from its ap-ex to from the vertex, in the cross section a triangle will be formed, This triangle will be an isosceles triangle.

In conclusion, the shape of the cross section formed from slicing the pyramid is a triangle.
