Question

Suppose f f, g g, h h, and j j are functions such that: f ( r ) f(r) represents the circumference (in cm) of a circle whose radius is r r cm. g ( C ) g(C) represents the radius (in cm) of a circle whose circumference is C C cm. h ( r ) h(r) represents the area (in cm2) of a circle whose radius is r r cm. j ( A ) j(A) represents the radius (in cm) of a circle whose area is A A cm2. Use function notation to represent the area of a circle whose circumference is 117 cm.

Answer 1

Can it be rounded up or down?
