  2. Find the lateral surface area and then find the total surface area. The volume of a cone-shaped hole is 49π ft3 . If the hole is 3 feet deep, what is the radius of the hole?

  3. Write the number in scientific notation or standard form. a. 6.93 x 106 c. 1.22 x 109 b. 8,930,000,000 d. 287,600,000 Line one passes through the points (–2, 2) and (1, 3). Line 2 passes through the points (3, 10) and (7, 22). Find the slope of each line. The slope of Line 1 is ___________ The slope of Line 2 is ___________ Which line has the greater slope? ________________ Determine whether the following relation represents a function. Yes ______ No ______ (7, –5), ( 2, –1), (6, –4), (4, –3)
