What is the volume of a cone with a height of 6 cm in the radius of 2 cm

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212

Find the distance of the blue line between the two labeled points. round to the nearest hundredth. a) 7.07 b) 7.21 c) 10 d) 5.12
