Question

find the radius and area of a circular sheet whose circumference is 157 CM (π= 3.14)​

Answer 1

Answer:

7.7 is the correct answer.

Answer 2

Answer:

Radius=25cm

Area of circle=1962.5cm²

Step-by-step explanation:

As we know circumference of circle is 2πr

then,

2πr = 157cm

r = 25cm

Now, area of circle = πr²

area = 3.14×25cm×25cm = 1962.5cm²

Area = 1962.5cm²
