Answer:

V =904.7786842 m^3

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

The diameter is 12 so the radius is  d/2 = 12/2 = 6

V = 4/3 pi 6^3

V = 288 pi

Let pi = 3.14

V =904.32

If we use the pi button

V =904.7786842

Answer:

105 feet or inches^2

Step-by-step explanation:

First we find the surface area of the base, (or the square.)

That is 25.

Next we find the areas of the triangle which is: \frac{1} {2} base×height

The area of one triangle is 20, so we multiply it by 4.

That is 80.

Finally, we add both surface area to find the total surface area.

That is 80 + 25 = 105

Hope that helped!

Answer:

x = 80

Step-by-step explanation:

x + 30 = 110 (opposite sides are congruent/equal)

x = 110 - 30 (subtract the 30 from both sides to get X by itself)

x = 80 (simplify)
