Circumference :
In geometry, the circumference (from Latin circumferens, meaning "carrying around") of a circle is defines as the linear or Circular distance around it.
It is given by the formula:
The Correct order to calculate the circumference of a circular lid
1 ) Measure the radius of the lid.
Radius will be measured
2 ) Multiply the radius by 2 to find the diameter.
Diameter = 2 × Radius
3 ) Multiply the diameter by π.
π × Diameter = Circumference
Then we will get the Circumference,
Answer:
40 in.^2
Step-by-step explanation:
Let's name the 2 shaded triangles: The left one is T1 and the right one is T2.
The area of a right triangle can be found using the equation (a*b)/2.
The 2 legs of T1 are 8 in. and 6 in. (from 10 - 4)
Area of T1 = = 24 in.^2
The 2 legs of T2 are 8 in. and 4 in.
Area of T2 = = 16 in.^2
Area of shaded region = 16 + 24 = 40 in.^2
