What is the area of the drumhead on the drum shown below? round to the nearest tenth

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. 

20 percentage, you can also do it on a calculator.
