Step-by-step explanation:
Area of Rectangle at the top =
Length x Width
Area of Quarter- Circle = 1/4 x Area of Circle
Area of Rectangle at the right = Length x Width
Total Area = Area of 2 Rectangles + Area of Quarter Circle
I will leave the answer in terms of pi as I'm not sure if you need to round off your answer.
the value of x is 8 cm.
<u>Step-by-step explanation:</u>
Correct Question : In the diagram, the radius of the outer circle is 2x cm and the radius of the inside circle is 6 cm. The area of the shaded region is 220π cm2. What is the value of x? Enter your answer in the box.
We have ,
the area of a circle = πr²
the outer circle area =
the inside circle area =
According to Question,
the outer circle area - the inside circle area = he shaded region
