Answer:

First one: Degree of 13, type monomial

Second one: Degree of 5, type trinomial

Third one: Degree of 8, type trinomial

Step-by-step explanation:

The degree of a polynomial is determined by the highest degree of its individual terms. To determine the degree of a term, add up the power values of the variables.

The type of the polynomial is determined by how many terms are being separated by an addition sign ( a subtraction sign is just the addition of the inverse of a number).

One term: Monomial

Two terms: Binomial

Three terms: Trinomial

Four terms and so on: Generally just called polynomials

The radius of a sphere is 3 inches. Which represents the volume of the sphere?
uranmaximum [27]

Answer:

volume of sphere  =  113.14inches³  or  

      36πinces³

Step-by-step explanation:

given the radius of a sphere = 3inches

volume of the sphere = ?

π = 3.14v 0r 22/7

 recall, the formula for finding the volume of a sphere is given to be = 4/3 πr³

so,

volume of sphere  =   4/3 πr³

volume of sphere  = 4/3 ×  22/7 ×  ( 3)³

volume of sphere  =  4/3 × 22/7 × 27

volume of sphere  =  (4 × 22 × 9)/7

volume of sphere  =  113.14inches³  or  36πinces³
