Suppose a sector of a circle with radius r has a central angle of θ. Since a sector is a fraction of a full circle, the ratio of
enot [183]

Answer:

Central angle of θ

\dfrac{A}{\pi r^2} =\dfrac{\theta}{2\pi}

A=\dfrac{\theta r^2}{2}, (\theta$ in radians)

Step-by-step explanation:

Suppose a sector of a circle with radius r has a central angle of θ.

Since a sector is a fraction of a full circle, the ratio of a sector's area A to the circle's area is equal to the ratio of the central angle of θ to the measure of a full rotation of the circle.

A full rotation of a circle is 2π radians.

This proportion can be written as:  \dfrac{A}{\pi r^2} =\dfrac{\theta}{2\pi}

Multiply both sides by \pi r^2

\dfrac{A}{\pi r^2} *\pi r^2=\dfrac{\theta}{2\pi}*\pi r^2

Simplify to get:

A=\dfrac{\theta r^2}{2}

Where θ is the measure of the central angle of the sector and r is the radius of the circle.

If the product of two numbers is positive, which of the following expressions must be true?
larisa86 [58]

Answer:

C. The factors had the same sign.

Step-by-step explanation:

Factors that had the same sign will have a positive product.

Two positive numbers will have a positive product.

For example, 3 times 3 is 9.

Two negative numbers will also have a positive product, because multiplying negative numbers by other negative numbers will cancel out the negative.

For example, -3 times -3 is 9.

So, C is correct
