Question

Jose’ has a circular rug on the floor of his bedroom. If the area of the rug is 16π square feet, what is the diameter of the rug?

Answer 1

Area of a circle is πr^2
so
16π = πr^2
the π's in both sides cancel out as it is a constant.
so it's
16 = r^2
r = √16
r = 4
so if radius so 4 then diameter is 8
because Radius is half the diameter.
