(2) r2
(3) πr2
(4) 2r2
Answers
Answer:
The Ans is πr2
Step-by-step explanation:
The Diameter of the inscribed circle is 8 units......... and therefore the radius is 4 units.
The Area of a circle of radius r units is A=πr2 .
Hope it helps U............... Ji
Answer:
- 1) 4r²
GivEn :-
- The radius of circle is r
- The circle is inscribed in a square
To Find :-
- The area of square
Diagram :-
- Refer to the attachment
Step-by-step explanation:
➠Now as given, the radius of a circle is r
➠Therefore, the diameter of the circle is 2r
( As diameter = 2 × radius )
➤ According to the diagram, it is clear that,
If a circle is inscribed in a square, then the diameter of the circle and the side of the square are of equal length!
➠ To get the area of the square, first we need to find out the value of each side of it.
➠ Side of square = Diameter of circle = 2r
➤ Now, we know the formula of area of a square,
➠ Area of square = side²
➠ Area = 2r × 2r = 4r²
➠ Therefore, the answer would be option 1)
