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:
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.
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=
