I NEED HELP PLEASE! :)

Answer:

<em>Hello There If you want to learn of the equation of the circle. Look at the circle first then.. The center-radius form of the circle equation is in the format will help you from that point. with the center being at the point (h, k) and the radius being "r". This form of the equation is really helpful, since you can easily find the of center and the radius.</em>

Hope it helps!

A(r) is a function that gives the area of ta circle with the radius r. It can be written in an equation form as A(r)=3.14r^2. wh

notsponge [240]

A(r)=3.14r^2, when r=5

A(5)=3.14(5^2)

A(5)=3.14(25)

A(5)=78.5 u^2
