Question

If the circumference of a circular sheet is 154 m find its radius. Also find the area of the sheet.

(π = 22/7)​

Answer 1

Answer:

Radius = 24.5m

Area = 590.25m²

Step-by-step explanation:

Circumference = 2 × Pi × radius

Let the radius be x,

So, to find x;

154 = 2 × 22/7 × x

154 = 44/7 × x/1

154 = 44x / 7

154 × 7 = 44x

1078/44 = x

24.5 = x

x = 24.5

So, radius = 24.5m

Therefore,

area = 22/7 × 24.5²

Answer 2

Answer:

49/2 is the radius

Step-by-step explanation:

circumference=2πr

circumference/2π = r

154÷(22×2)/7= r

154×7/44= r

14×7/4= r

7×7/2= r

49/2= r
