If the shaded region is the circle (which it is),
The area of it is 78.5cm²
You can find the area of a circle by using the formula: pi • radius squared
In this case, the question states to use 3.14 for pi so our equation would look like:
3.14 • 5 • 5 (5 squared is same as 5 times5)
And that is how you get 78.5cm²
Find the area of the square
Find the area of the circle
Subtract the area of the circle from the area of the square.
area of square = 10 x 10 = 100 sq. Cm
Area of circle = pi x r ^2 = 3.14 x 5^2 = 78.5 sq. Cm
area of shard region = 100 - 78.5 = 21.5 cm^2

Answer:
Step-by-step explanation:
The time is inversely related to the number of people working so that as the number of people working increases, the time required decreases
t = k p
divide both sides by p
t/p =k
