A cone is created from a paper circle with a 90° sector cut from it. The paper along the remaining circumference of the circle is the base of the cone. Find the radius of the base of the cone. Round to the nearest hundredth.

since you have neglected to mention the radius of the paper circle, it's hard to give a numeric answer.
Suffice it to say that since 1/4 of the paper has been removed, the radius of the cone's base is 3/4 the radius of the original paper circle.
