The volume of a right circular cone is 1,780.38 in3. If the height of the cone is 21 in, what is the diameter of the cone? (Use = 3.14)

18 inches

Step-by-step explanation:

formula is      V = π* r^2* h/3.

h = 21. 21/3 = 7.

7*3.14 = 21.98.

1,780.38/21.98 = 81.

√81 = 9.

r = 9

d = 2r

9*2 = 18 inches.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
