babunello [35]

Answer:

k= -1

Step-by-step explanation:

To find k, use the points and the m =-7 in the slope formula:

m=\frac{y_2-y_1}{x_2-x_1}\\\\-7=\frac{-8-k}{5-4} \\\\-7 = \frac{-8-k}{1}\\\\-7=-8-k\\\\k = -8+7\\\\k=-1

The main show tank has a radius of 60 feet and forms a quarter sphere where the bottom of the pool is spherical and the top of t
svetlana [45]

The given radius is = 60 feet

The volume of the sphere is given by = \frac{4}{3} \pi r^{3}

So we will find the volume of the sphere using radius as 60 and pi as 3.14

Volume = \frac{4}{3}*3.14*60*60*60 = 902059.20 cubic feet

As quarter of anything is defined as its one-fourth part, so here the volume of the quarter of sphere can be calculated by finding one fourth of the calculated volume.

So volume of quarter sphere = \frac{902059.20}{4}

= 225514.80 cubic feet

And rounding this to nearest whole number we get 225515 cubic feet as the answer.
