Look at picture ; -;
it's v= four thirds times pie times r to the power of 3. just a comma at the end ignore that.

Step-by-step explanation:

turn the 4/3 into a decimal.=1.33

multiply 1.33*3.14=4.1762

i cant see the rest is it r³?

The answer to your question is x = 8

Step-by-step explanation:

Data

Isosceles triangle

side 1 = √80

height = 8

x = ?

Process

To solve this problem, divide the triangle in two equal triangles and find x/2 using the Pythagorean theorem.

1.- Calculate x/2 (m)

hypotenuse = √80

long leg = 8

short leg = x/2 = m

                   (√80)² = 8² + (m)²

-Solve for x/2

                    80 = 64 + (m)²

                    80 - 64 = m²

                     m² = 16

                     m = √16

                     m = 4

2.- Find x

x = 2m

x = 2(4)

x = 8
