Can somebody me with these to questions how do you find the area of the circle

13)

Circumference (C) = 2π·r

11π = 2π·r

11/2 = r

Area (A) = π·r²

             =  π·(11/2)²  

            = 121π/4

           ≈ 94.985 in²

14)

diameter = 2r

          42 = 2r

           21 = r

Area (A) = π·r²

             =  π·(21)²  

            = 441π

           ≈ 1384.74 in²

$280/1384.74 in²

x = $0.20

about 20 cents per square inch

//blooming serenity//

beautiful in the morning

mysterious at night

wonderous nature souring

with all it's mystical might

the flower that blooms

to the fox that looms

nocturnal creatures

with various features

a blooming flower soon in sight

as a new little hatchling fears to take flight  

afraid to leave it's calming nest,

but dear little bird, mother knows best

as sure as there are stars in the sky,

life is not about who, where what, when or why-

it's the journey that follows

adventures we swallow

of   nature's deep wonders,

natural disasters and storm's thunders.

blooming serenity

life and nature, truly is heavenly.
