The scatter plot shows a hiker’s elevation above sea level over time. The equation of the trend
line shown is y = 8.77x + 686. To the nearest
whole number, predict what the hiker’s elevation
will be after 145 minutes.

Step-by-step explanation:

please explain question in details

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.
