what is expression?

An expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it. Let us understand how to write expressions. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:

  • Constant: A constant is a fixed numerical value.
  • Variable: A variable is a symbol that doesn't have a fixed value.
  • Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.
  • Coefficient: A coefficient is a number that is multiplied by a variable in an expression.

Given:

(–2)5

Using integer (-)*(+)= (-)

=-2*5

=-10

Hence, the expression is -10.

How to find the volume of the cone

Answers

Answer:

The closest measurement to the volume of hat is 84.82 in.³.

Step-by-step explanation:

Given:

The dimensions of hat are height(h) 9 inches and diameter(d) 6 inches.

Now, to find the volume of cone:

Putting the formula (1)/(3)\pi r^(2)h.

Radius(r) is not given, finding the radius:

Radius(r)=half of the diameter(d)

r=(d)/(2)

r=(6)/(2)

r=3.

Then, (1)/(3)\pi r^(2)h

=(1)/(3)*\pi *3^(2)*9

=(1)/(3)*3.14*9*9 (\pi =3.14)

=(1)/(3) *254.34

=(254.34)/(3)

=84.78 in.³

So, the volume is 84.78 in.³ .

Therefore, the closest measurement to the volume of hat is 84.82 in.³.
