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:
sum of interior angles of the octagon is 1080 degree
Step-by-step explanation:
forluma:
(n-2)*180 degree
since octagon has 8 sides
(8-2)*180 degree
6*180
1080 degree
Step-by-step explanation:
<u>Step 1: Subtract 18 from both sides</u>
<u>Step 2: Divide both sides by 6</u>

Answer:
7.2 hrs
Step-by-step explanation:
divide 24 by 100 than multiply it by 30 to get the answer.
Answer:
This is 
of your money.
Step-by-step explanation:
We have a decimal number, and we want the answer to be a fraction. To transform a decimal number into a fraction, we multiply both the numerator and the denominator by 10 until none of them have decimal parts. So
This is of your money.
