Question

If the circumference of a circular sheet is 154m, find its radius.[Take π=22/7] *

1886m²

24.5m

13m



​

Answer 1

$2 \times \frac{22}{7} \times r = 154$

$\frac{44r}{7} = 154$

$\frac{154 \times 7}{22}$

$49$

So 49 ÷ 2 = 24.5cm is the solution

Answer 2

Answer:

circumference of the circular sheet is given 154 m

formula for circumference is 2πr

Now, 2πr = 154

2×22/7×r = 154

r = 154 ×7/2×22

r = 49/2 i.e., 24.5m

therefore required radius is 24.5 m
