Find the distance Between points (3,7) and (-3,4).

the distance is 3√5 !

Step-by-step explanation:

Since the points form a triangle, you can use Pythagorean theorem to solve this.

Side A is 3 Units, and side B is 6. The letters do not matter when corresponding them to the sides.

So Pyth Theorem = a^2 + b^2 = c^2

And c^2 is the distance we must find

So a^2 = 9

b^2 = 36

So 36 + 9 = 45

To find C, you must root c^2

So sqrt of 45 is 6.7

The distance between points (3,7) and (-3,4) is 6.7 units.

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
