Find the surface area and volume of a sphere with a radius r=0.8ft. round your answer to the nearest tenth

To solve this problem you must apply the proccedure shown below:

1. You must use the formula for calculate the volume of a sphere and the formula for calculate the surface area of a sphere, which are:

Where is the radius ()

2. The volume is:

3. The surface are is:

The answer are: The volume is and the surface area is

answer: 1 2 3 6

step-by-step explanation:

1x6=6 2x3=6

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
