Given a sphere with radius r, the formula 477 gives A. the volume
B. the surface area
C. the radius
D. the cross-sectional area

Hello, My answer is B) The surface area of the sphere. or B) The surface area.

Step-by-step explanation:

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

i will pick c put check it over to be sure
