Question

what is the length of the rope by which a horse should be tied so that it can graze an area of 3850m​

Answer 1

GIVEN,

ROPE LENGTH / RADIUS ( R )= ? LET X

AREA OF CIRCLE = 3850

NOW

AREA OF CIRCLE (A) = [22/7] * X^2

[3850 * 7] / 22 = x^2

1225 = x^2

√ 1225 = x

x = 35

Hence the rope should be 35 m

Answer 2

Answer:

35m answer

Step-by-step explanation:

area of circle =pi R2

3850 =22/7×r2

R2 = 3850×7/22

R2 = 1225m

r =√1225

r = 35 m

Hence, the length of rope should be 35m
