Solution:

<u>Note that:</u>

  • Area of circle: πr²
  • r = 11 ft.

<u>Substitute the radius in the expression to find the area of the circle.</u>

  • (π)(r²)
  • => (22/7)(11²)
  • => (22/7)(121)
  • => 380.29 ft² (Rounded)

The formula to find area of circle is:

\boxed{ \mathfrak \red{ area = \pi r ^{2} }}

Where,

  • r is radius
  • the value of pi is constant

In our case,

  • r = 11 ft
  • pi = 3.14

\orange { \sf \: area = 3.14 \times  {11}^{2} }

\green{ \sf \: area = 3.14 \times 121}

\blue{ \sf \: area = 379.94 \:  {ft}^{2} }

A geologist noticed that a land along a fault line moved 24.8 centimeters over the past 175 years . On average, how much did the
olasank [31]

Answer:

On average, the land moved 0,14 cm each year.

Step-by-step explanation:

To know how much did, on average, the land move,  we should divide the total number of cm over the total number of years:

x=24.8 cm/175 years

x=0,1417 cm each year

If we divide years over cm we will get x in years each cm, which is wrong.

Because the problem asks for the answer rounded to the hundredths place:

x= 0,14 cm each year
