Stells [14]

Answer:

V =\frac{1}{3} \pi r^2 h

And replacing we got:

V = \frac{1}{3} (3.14) (5in)^2 (2.5in) = 65.42 in^3

And the best option would be:

65.42 Inches cubed

Step-by-step explanation:

For this case we have the following info given:

h =2.5 in represent the height of the cone

r = 5 in represent the radius

And the volume of the cone is given by;

V =\frac{1}{3} \pi r^2 h

And replacing we got:

V = \frac{1}{3} (3.14) (5in)^2 (2.5in) = 65.42 in^3

And the best option would be:

65.42 Inches cubed

Use the Perfect Square Trinomial and provide the first step to calculating 382 without a calculator.
dusya [7]

Answer:

(40-2)^2

Step-by-step explanation:

Given: (38)^2

To find: the correct option

Solution:

A binomial polynomial is a polynomial consisting of two terms.

A trinomial polynomial is a polynomial consisting of three terms.

On multiplying a binomial (x-y) to itself, a perfect square trinomial (x-y)^2 is obtained.

Here, 38=40-2

So, (38)^2=(38)(38)=(40-2)(40-2)=(40-2)^2

Here, (40-2) is a binomial and it is multiplied to (40-2) to get a perfect square trinomial (40-2)^2
