Answer:
Step-by-step explanation:
we know that
The <u><em>Midpoint Theorem</em></u> states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side.
so
In this problem
solve for x
Multiply by 2 both sides
subtract 2x both sides
Adds 1 both sides
<h3>Calculate the volume of the sphere</h3>
To start finding the volume of this sphere, we get the following data:
- π = 3
- r = 2 ft²
To find the volume we apply the following formula:
, where
- v = volume
- π = pi
- r = radius
We substitute our data in the formula and solve:
Substituting values into the equation
Calculate exponent cubed
Multiplying
Therefore, the volume of the sphere is 32 ft³.
