Sheldon is painting a wall in his house and is using a paint roller. The roller has a radius of 1 inch and a height of 8 inches. How many square inches of space can Sheldo paint with one revolution of paint roller? Round to the nearest tenth.

(note i put the graph in so plz )the graph shows the amount of water that remains in a barrel after it begins to leak. the variable x represents the number of days that have passed since the barrel was filled, and y represents the number of gallons of water that remain in the barrel. what is the slope of the line

25 ! the line of best fit is h = 5a + 86. predict the height at age 16.

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0
