The volume of a spherical sculpture is 256 ft³. rhianna wants to estimate the surface area of the sculpture. to do the estimate, she approximates π using 3 in both the surface area and volume formulas for a sphere. using this method, what value does she get for the approximate surface area of the sculpture?

An observer(o) spots a plane(p) taking off from a local airport and flying at a 29 degree angle horizontal to her line of sight and located directly above a tower(t). the observer also notices a bird circling directly above her. if the distance from the plane(p) to the tower(t) is 6,000ft., how far is the bird(b) from the plane(p).
