The volume of a right circular cone that has a height of 13 m and a base with a diameter of 3.4 m. Round your answer to the near
Mamont248 [21]

Answer:

The volume of right circular cone having height = 13 \ m and Diameter =   3.4 \ m is 39.4\ cubic\ meter.

Step-by-step explanation:

Diagram of the given scenario is shown below.

Given that

Height of a right circular cone is 13 \ m.

Diameter of the right circular cone is 3.4 \ m.

To find: The volume of a right circular cone.

So,  From the question,

                                       Height = \ 13 \ m\\diameter = 3.4\ m

                                       Radius = \frac{diameter}{2}= \frac{3.4}{2}

 ⇒                                  Radius = 1.7\ m

Now

    Volume of right circular cone = \frac{1}{3}\pi  r^{2}h

                                                      =\frac{1}{3}\times\frac{22}{7} \times (1.7)^{2}\times 13

                                                      =   \frac{826.54}{21}

                                                      = 39.4\ cubic\ meter.

Therefore,

The volume of right circular cone having height = 13 \ m and Diameter =   3.4 \ m is 39.4\ cubic\ meter.

Answer:

The degree of the polynomial is 3

Step-by-step explanation:

Given:

a^3+3a^2-5a

To Find:

The degree of the polynomial= ?

Solution:

The degree of the polynomial   is the value of the greatest exponent of any expression (except the constant ) in the polynomial. To find the degree all that you have to do is find the largest exponent in the polynomial

Here in the given polynomial

a^3+3a^2- 5a

The terms are

a^3

3a^2

5a

The term  a^3 has  the largest exponent of  3

Note:  The degree of the polynomial does not depend  on coefficients of the terms
