The area of a sector of a circle with a radius of 4 centimeters is 2.512 square centimeters. The estimated value of ╥ is 3.14. The measure of the angle defining the sector is

Answers

The equation for the area of a sector of a circle is expressed as the product of pi, square of the radius and the ratio of the angle of the sector and 360 degrees.

Area = πr^2 (α / 360°)

We obtain the angle by manipulating the equation.

α = (Area x 360°) / πr^2 
α = (2.512 cm^2 x 360°) / (π x 4^2)
α =35.98°

I see your doing trinomials. It would be prime because nothing adds to negative ten and multiplies to six.

multiplying polynomials

(3m-1)(8m+7)

Answers

(3m-1)(8m+7)=3m\cdot 8m+3m\cdot 7-1\cdot 8m-1\cdot 7=\n \n=24m^2+21m-8m-7=24m^2+13m-7


The product of (3m-1)(8m+7) is 24m² + 13m - 7.

To multiply the polynomials (3m-1)(8m+7), we can use the distributive property. We multiply each term in the first polynomial by each term in the second polynomial and then combine like terms.

(3m-1)(8m+7) = 3m(8m) + 3m(7) - 1(8m) - 1(7)

Simplifying this expression, we get:

24m² + 21m - 8m - 7

Combining like terms, we have:

24m² + 13m - 7

Therefore, the product of (3m-1)(8m+7) is 24m² + 13m - 7.

We can also see that this product represents a quadratic polynomial. The highest power of the variable "m" is 2, which is indicated by the term 24m². The other terms, 13m and -7, represent the linear and constant parts of the polynomial, respectively.

The result is a quadraticpolynomial in standard form, where the terms are arranged in descending order of the variable's exponent. In this case, the quadratic polynomial is 24m² + 13m - 7.
