What is the area of the drumhead on the drum shown below? Round to the nearest tenth
Harman [31]
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.

The average of four numbers is 38, and the average of the first two numbers is 42, and the average of the last three numbers is
diamong [38]

Answer:

40

Step-by-step explanation:

let the numbers be a+b+c+d.

the average of 4 numbers is 38

; (a+b+c+d)/4 = 38

(a+b+c+d) = 152 ......equ1

the average of the first two numbers is 42

; (a+b)/2 = 42

(a+b) = 84 ...... equ2

the average of the last three numbers is 36

; (b+c+d)/3 = 36

(b+c+d) = 108 .....equ3

substitute equ3 into equ1

a + 108 = 152

a= 152 - 108

a = 44

input the value of a into equ2

44 + b = 84

b = 40

the second number is 40.

I hope this helps.

Estimate the solution to the system of equations. 7x−y=7<br><br> x+2y=6<br> ​
ElenaW [278]

Answer:

I am not sure how your teacher wanted you to estimate the answer but I solved it for you. Hopefully this helps.

Step-by-step explanation:

7x-y=7

x+2y=6

14x-2y=14

x+2y=6

add both equations

15x=20

x=20/15

x=4/3

x+2y=6

4/3+2y=6

2y=6-4/3

2y=18/3 -4/3

2y=14/3

divide both sides by 2

y= 14/3 divided by 2

y=14/3(1/2)

y=14/6

2y=
