a) Based on the known dimensions of the balls, you know that the height of the container is 13*3=39 cm, while the radius is 13/2=6.5cm. Using the formula for the volume of a cylinder, you get $\pi r^2 h= \pi \cdot 6.5^2 \cdot 39\approx 5177$ cubic centimeters.

b) The volume of a single one of the balls can be found with the formula for the volume of a sphere, or $\frac{4}{3}\pi r^3$ , or in this case about 1150 cubic centimeters. Multiplying this by 3, you get about 3451 cubic inches.

c) 3451/5177 is almost exactly 2/3, or about 66.67%. Hope this helps!

Let g(x) = 2x2 - 11x. Find g(-1).

marusya05 [52]

Hey there :)

g ( x ) = 2x² - 11x

For g ( - 1 ) , you need to substitute - 1 in place of x

g ( - 1 ) = 2 ( - 1 )² - 11 ( - 1 )
= 2 ( 1 ) + 11
= 2 + 11
= 13 → Your answer
