Circumference of circular sheet =154m
2πr=154
2×22/7×r=154
r=154×7/2×22
r=49/2
r=24.5m
Area of sheet=πr²
=22/7×24.5×24.5
=22/7×245/10×245/10
=1886.5m²
2πr=154
2×22/7×r=154
r=154×7/2×22
r=49/2
r=24.5m
Area of sheet=πr²
=22/7×24.5×24.5
=22/7×245/10×245/10
=1886.5m²

Given data:
- Circumference of the circular sheet = 154m
- π = 22/7
Finding the radius:
- The formula to find the circumference of a circle is C = 2πr, where C is the circumference and r is the radius.
- Given that the circumference is 154m and π = 22/7, we can write the formula as 154 = 2 * 22/7 * r.
- Solving for r, we get r = 154 / (2 * 22/7) = 154 / (44/7) = 154 * 7 / 44 = 154 * 7 / 44 = 24.5m.
Therefore, the radius of the circular sheet is 24.5m.
Finding the area:
- The formula to find the area of a circle is A = πr^2, where A is the area and r is the radius.
- Substituting the radius value we found earlier, we get A = (22/7) * (24.5)^2 = (22/7) * 600.25 = 1885.5 square meters.
Therefore, the area of the circular sheet is 1885.5 square meters.
