Answer:

5

Step-by-step explanation:

When subtracting a negative number, you will add it.

This is because the negative signs of the subtraction sign and the negative number will cancel out.

This will change the subtraction sign to a positive sign and will switch the negative sign on the number to a positive one.

So, 3 - (-2) will change to 3 + (2)

3 + 2

= 5

In a circle of radius 10 cm, a sector has an area of 40 (pi) sq. cm. What is the degree measure of the arc of the sector?
Rashid [163]

Answer:

144°

Step-by-step explanation:

First, find the area of the circle, with the formula A = \pir²

Plug in 10 as the radius, and solve

A = \pir²

A = \pi(10²)

A = 100\pi

Using this, create a proportion that relates the area of the sector to the degree measure of the arc.

Let x represent the degree measure of the arc of the sector:

\frac{40\pi }{100\pi } = \frac{x}{360}

Cross multiply and solve for x:

100\pix = 14400\pi

x = 144

So, the degree measure of the sector arc is 144°
