There is no image posted. However, I will tell you how to solve for the area of a drum head.
Drum head is a circle shape. We will use the formula of finding the area of a circle to solve for the area of a drum head.
Area of a circle = π r²
π is pi. It is equivalent to 3.14. Though there are still a lot of numbers after 4. To ensure uniformity, π is 3.14
r is radius. It is the line from the center of the circle to the edge of a circle.
if the diameter of a circle is given, simply divide the diameter by 2 to get the radius.
Diameter is the line that starts from one end of the circle to the other passing through the midpoint of the circle.
Example:
The drum head has a diameter of 10. What is the area.
diameter is given, so we need to get the radius: 10 ÷ 2 = 5
Area = π r²
= 3.14 * 5²
= 3.14 * 25
Area = 78.50 square unit
Area is always in a square unit.
Answer:
64
Step-by-step explanation:
i calculated using https://www.calculator.net/triangle-calculator.html :/
First we need to find the slope of the line.
slope = y1-y2/x1-x2 = 4-1/3-(-3) = 3/6 = 1/2
So, the slope is 1/2
Now, we need to find the y-intercept by using the equation y=mx+b
y=mx+b
4=1/2(3)+b
4=3/2+b
-3/2 -3/2
5/2=b
So, the equation is y=1x/2+5/2 which is also C. y-3=1/2(x+1)
HPE THIS HELPS!!!
Answer:
-1
Step-by-step explanation:
To find the slope of a line, you would need to use the slope formula, and that is 
This equation should be used every time you need to find a slope with two given points. If you remember this, you would find questions like this more easy.
First, you would need to plug in your coordinate points into the formula.
You would plug -7 in y2, 2 in y1. And then you will plug in 4 in x2, and -5 in x1.
Your equation should look like this:
Then you solve.
For the top portion of your equation you would get -9. The -5 turns into a positive 5 because when you carry the negative over (distribute it), the negative cancels out and turns into a positive. When you add the 5 and the 4 together, it will get you 9. The bottom portion of the equation will be 9.
Your equation should now look like this:
Now, you divide.
When you divide, the two 9's end up as a whole, and you keep the negative since the negative doesn't cancel out in this situation. When you finish dividing, you would get -1.
Your FINAL answer would be -1.
The equation that you should use to solve this is (13 + 1/4) - (6 + 2/3) = 6 and 7/12
