Answer:

The correct answer is second option

3π in²

Step-by-step explanation:

<u>Points to remember</u>

Area of circle = πr²

Where r is the radius of the circle

<u>To find the area of outer ring</u>

Here radius of large circle = 1 + 1 = 2 in and

radius of small circle = 1 in

Area of outer ring  = Area of large circle - area of small circle

 =  π2² -  π1²

 = 4π - π

 = 3π in²

The correct answer is second option

3π in²

Answer:

3pi

Step-by-step explanation:

To find the area of the outer ring, we must first find the areas of the two circles. The red circle has a diameter of 2 which means the radius is 1. So the area of the red circle is pi.

Finding the area of the whole target, the radius is 2. So the total area is 4 pi.

So the area of the outer ring is 3pi

Which two points lie on the circumference of this circle? A. (1.3,0.5) B. (2.5,1.5) C. (3.4, -0.2) D. (3.9,0.7) E. (6.0,-2.0)
liq [111]

Step-by-step explanation:

(x-2)²+(y+5)²=25

option C (3.4,-0.2)

LHS= (3.4-2)²+(-0.2+5)²

= (1.4)²+(4.8)²

= 1.96+23.04

= 25

option E(6,-2)

LHS= (6-2)²+(-2+5)² = 4²+(-3)² = 16+9 = 25

Doss [256]

SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the given inequality

-18x+3

STEP 2: Solve for x

\begin{gathered} -18x+3\frac{-45}{18} \\ x>-\frac{5}{2} \\ x>-2.5 \end{gathered}

STEP 3: Plot the number line for that represents the final solution

Hence, the number line that best represents the final solution can be seen in the number line below:
