Question

the area of a circular field is 550 metre square a bigger field has it radius 3 times the radius of the smaller find the area of the biggest field​

Answer 1

Step-by-step explanation:

Let the bigger field be b

Let the smaller field be s

Area of s=550 m²

r=x

So,

Area=πr²

550=22/7*x*x

550=227*x²

x²=7/22*550

x²=175

x=√175

x=13.23 m

So, Radius of s=13.23m

If, Radius of b=3*(radius of s)

So, Radius of b=3*13.23

=39.69 m

So,Area of b=πr²

Area=22/7×39.69*39.69

Area=4948.94 m²
