An arc subtends a central angle measuring \dfrac{\pi}{2}
Agata [3.3K]

Arc Length is 1/4th of the circumference .

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

Here we need to find fraction of the circumference is this arc when An arc subtends a central angle measuring \dfrac{\pi}{2} radians ! Let's find out :

We know that circumference of an arc subtending a central angle of x is :

⇒ Arc = \frac{Angle}{360}(2\pi r)

⇒ Arc = \dfrac{\frac{\pi}{2}}{360}(2\pi r)

⇒ Arc = \frac{90}{360}(2\pi r)

⇒ Arc = \frac{90}{90(4)}(2\pi r)

⇒ Arc = \frac{1}{4}(2\pi r)

⇒ Arc = \frac{1}{4}(Circumference)

Therefore , Arc Length is 1/4th of the circumference .

Rashid [163]

Answer:

5 classes.

Step-by-step explanation:

You can use the 2^k rule to determine the number of classes for a frequency distribution.

The 2^k rule says that 2^k\geq n where

k is the number of classes

n is the number of the data points

We know that the number of data points is n = 20.

Next, we start searching for k so that we can get a number 2 to the k that is larger that the number of data points.

2^4=16\\2^5=32

This suggests that you should use 5 classes.

HELP IM BEING TIOMEEEEEEEEDDDDDDDDDDDDDDDD
Anton [14]

Answer:

-2.1

Step-by-step explanation:

x= 4/5

you put in 4/5 where x is supposed to be so you get: -2/5 - 4/5 + (-9/10)

-2/5 - 4-5 = -6/5

-6/5= -12/10

-12/10 + -9/10= -21/10 = -2.1

14. Jeremy plants flowers in a circular bed,
GrogVix [38]

The area of the circular shaped patio is: 172.7 ft²

<h3>What is the Area of a Circle?</h3>

Area of a circle = πr² [r is given as the radius of the circle].

The area of the patio = area of the larger circle - area of the smaller circle.

Radius of the larger circle = 8 cm

Radius of the smaller circle = 3 cm

π = 3.14

Area of smaller circle = πr² = (3.14)(3²)

Area of smaller circle = 28.26 cm²

Area of bigger circle = πr² = (3.14)(8²)

Area of bigger circle = 200.96 cm²

The area of the patio = 200.96 - 28.26

The area of the patio = 172.7 ft²
