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?

Titus works at a hotel. part of his job is to keep the complimentary pitcher of water at least half full and always with ice. when he starts his shift, the water level shows 4 gallons, or 128 cups of water. as the shift progresses, he records the level of the water every 10 minutes. after 2 hours, he uses a regression calculator to compute an equation for the decrease in water. his equation is w –0.414t + 129.549, where t is the number of minutes and w is the level of water. according to the equation, after about how many minutes would the water level be less than or equal to 64 cups?
