Answer 1

Step-by-step explanation:

A≈198.94cm²

that's right answer.

Answer 2

Given

Circumference of Circle is 50cm

To Find

Area of the Circle

$\sf\huge\bold{\underline{\underline{{Solution}}}}$

➜Circumference means the total length of the outer boundary of the Circle.

C=2πr

=>Circumference of Circle = 2πr

=>Circumference of Circle= 2×22/7×r

=>50= 44/7 × r

=>50× 7/44 = r

=>25× 7/22 = r

=>175/22= r

=>radius=7.95cm

Area of circle= πr²

=>Area of circle = 22/7×(7.95)²

=>Area of circle= 3.14× 63.20

=>Area of circle=198.45cm²

Extra information=>

Circle have infinite number of radius which can be drawn from any point.

=>Circle have no vertex nor sides

=>If any two circle have equal radius then the two circles are said to be congruent.

=>A circle is a figure which can be inscribed in any other figure like such as rectangle, square etc.
