Over the last 2.5 years, the water level in a lake has changed by -0.3 feet per year. Scientists predict that the water level will continue to go down for the next 5 years at a rate of 0.4 feet per year.

Based on this information, Andrew made several claims. Determine whether each of the claims he makes is true or false.

A
In the last 2.5 years, the water level has decreased 0.75 feet.

True False
B
The overall change of the water level after 7.5 years will be -2.75 feet.

True False
C
The change in water level each year for the next 5 years will be -0.4 feet.

True False
D
The overall change in water level for the next 5 years is equal to 5(0.4).

For every corresponding pair of cross sections, the area of the cross section of a sphere with radius r is equal to the area of the cross section of a cylinder with radius and height 2r minus the volume of two cones, each with a radius and height of r. a cross section of the sphere is and a cross section of the cylinder minus the cones, taken parallel to the base of cylinder, is the volume of the cylinder with radius r and height 2r is and the volume of each cone with radius r and height r is 1/3 pie r^3. so the volume of the cylinder minus the two cones is therefore, the volume of the cylinder is 4/3pie r^3 by cavalieri's principle. (fill in options are: r/2- r- 2r- an annulus- a circle -1/3pier^3- 2/3pier^3- 4/3pier^3- 5/3pier^3- 2pier^3- 4pier^3)
