Question

Find area of circle circumference or area

Answer 1

closest option B (50.24)

Step-by-step explanation:

A=πr²

= π×4×4

=π×16

=50.265m²

Answer 2

Area:

50.24 m^2

Step-by-step explanation:

The formula for the area of a circle is A = πr²,

where:

• A = area,

• r = radius

Diagram:

`\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\qbezier(2.3,0)(2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,-2.121)(0,-2.3)\qbezier(2.3,0)(2.121,-2.121)(-0,-2.3)\put(0,0){\line(1,0){2.3}}\put(0.5,0.3){\bf\large 4\ m}\end{picture}`

Plug in the data. I'll use 3.14 for pi.

`\bf{A=\pi *4^2}\\\bf{A=3.14*16}\\\bf{A=50.24\:m^2}`

Hence, area = 50.24 m^2
