Plz answer #1 my sister needs to know

answer:

r=sqrt(24pi)/pi and d=(2*sqrt(24pi))/pi     pi=3.14; sqrt=square root or ^(1/2)

step-by-step explanation:

the area of the circle is a=pi*r^2

a=24 feet squared so

pi*r^2=24 divide each side by pi to solve for r^2

r^2=24/pi multiply by sqrt to solve for r

r=sqrt(24/pi) multiply numerator and denominator by sqrt(pi) to simplify

r=(sqrt(24pi))/pi

d=2r so

d=(2*sqrt(24pi))/pi
