Find the area of the circle.
A = pi x r x x
= 3.14 x 4 x 4
= 50.24
50.24 /2 = 25.12 cm2

If we are given the radius of a circle, evaluate how to find it's diameter?
Double Points if you can write an expression in terms of d for diameter, and r for radius.
To find diameter, multiply the radius by 2 or add the radius twice.
Bonus: d = 2(r) or d = r + r

If we are given the diameter of a circle, evaluate how to find it's radius?
Double Points if you can write an expression in terms of d for diameter, and r for radius.
To find radius, take half of the diameter.
Bonus: r = (d / 2)
