Question

if the circumference of the circular sheet is 154 M and find its radius and also find its area of sheet

Answer 1

Circumference=154
Circumference=2πr
154=2×22/7×r
r=(154×7)/2×22
r=22/44
r=1/2 M

Now, Area of circle=πr×r
Area=2×22/7×1/2×1/2
Area=11/7
Area=1.57 m sq.

Answer 2

Given :

• If the circumference of the circular sheet is 154M.

To find :

• What it its radius and also find its area of sheet.

Using formula :

★ Area of circle = πr².

Calculations :

→ 2 × 22/7 × r = 154

→ 7 = 153/2 × 7/22

→ 49/2

Therefore, 49/2 is its radius.

→ 22/7 × 49/2 × 49/2

→ 1,886.5 m²

Therefore, 1,886.5 m² is the area of sheet.
