An arc subtends a central angle measuring

Mathematics
1 answer:
barxatty [35]3 years ago
6 0

Answer:

The arc is one-third of the circumference.

Step-by-step explanation:

The area of a circumference = 2πr

C = 2πr ... (1)

If an arc subtends a central angle measuring 2π/3 rad,

The length of the arc = rθ

Given θ = 2π/3

Length of the arc L = r(2π)/3

L = 2πr/3... (2)

L = 1/3(2πr)

Since C = 2πr

L = 1/3C

This shows that the arc is one-third of the circumference.

Sebuah balok berukuran panjang 3 cm, lebar 4 cm, dan panjang diagonal ruang 13 cm. Volume balok adalah
kramer

Answer:

V=144\ cm^3

Step-by-step explanation:

#We use the base diagonal and the height diagonal to calculate the beam's height:

h=\sqrt{13^2-(4^2+3^2)}\\\\h=12\ cm

#The volume of the beam can then be calculated as:

V=lwh\\\\=4\times 3\times 12\\\\=144\ cm^3

Hence, the beam's volume is 144\ cm^3

What is the value of x?
Amanda [17]
There is a formula for Sum of interior angles of a polygon:
Sum = 180(n-2)
This figure has 7 sides, n = 7
Sum = 180(7-2) = 900
Add up all the given angles, 
Subtract from 900,
This will give you value of x.
