Cellular telephones send messages with a circular area called a cell. Suppose a cell has a radius of about 1000 cm. Find the area of the cell.

Asked:

  • Find the area of the cell.

Given:

  • A radius of 1000cm

Operation/Formula needed to solve the problem:

[tex] \bold{A=πr²}[/tex]

Solution:

[tex] \bold{A=πr²} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ ={ \bold{3.14 \times 1000}} \\ = { \boxed{ \bold{3140{ \bold{cm}^{ \bold{2}}}}}} \: \: \: \: [/tex]

Answer:

  • The area of cell is 3140cm²
