Question

The circumference of a circle is 19 ft.

What is the area, in square feet? Express
your answer in terms of T.

Answer 1

The area is approximately 28.73ft²

Explanation:

Given: Circumference = 19 ft

The necessary formula area,

Area: A = πr²

Circumference: C = 2πr

Combine:

A =
`(C^(2) )/(4\pi )`

A =
`(19^(2) )/(4\pi ) \\\\ (361 )/(4\pi )`

A = 28.72747
