Question

if the area of a circular field is 2464 m2 and circumference is 1.76m. then find rhe radius of the circle​

Answer 1

Step-by-step explanation:

area of circle = 22/7 r2

2464m2= 22/7 r2

2464*7/22= r2

112*7 = r2

784= r2

r = √784m2

r= 28 m

Answer 2

Answer:

r = 28m

r = 0.28m

Step-by-step explanation:

Let's assume radius = r

Area = π$r^{2}$ = 2464

$r^{2}$ = 2464 x $\frac{7}{22}$= 112 x 7 = 16 x 7 x 7 = $(28)^{2}$

r = 28m

Again, Circumference = 2πr = 1.76

r =1.76 x $\frac{7}{44}$ = $\frac{176}{100}$ x $\frac{7}{44}$ = 0.28m

Comparing the two results, one can see that one is 100 times the other.

Therefore, there must be an error in the given data.
