Keith_Richards [23]

Answer:

The area of the logo is $18.84\ ft^{2}$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The area of a semicircle is equal to

$A=\frac{1}{2}\pi r^{2}$

so

The area of the logo is equal to multiply by 3 the area of one semicircle

$A=\frac{3}{2}\pi r^{2}$

we have

$r=4/2=2\ ft$ -----> the radius is half the diameter

substitute

$A=\frac{3}{2}(3.14)(2)^{2}=18.84\ ft^{2}$
