cost of building a fence around a circular field is rs 7700 at rs 14 per foot.area of circular field???

ans(24062.5) anyone pls help

ok thank u

To find the area of a circular field, we need to know the total cost of building a fence around it as well as the cost per foot. In this case, we have the total cost of Rs 7700 and the cost per foot is Rs 14.

To find the radius of the circular field, we can divide the total cost by the cost per foot:

Radius = Total Cost / Cost per foot
Radius = 7700 / 14
Radius ≈ 550

Now that we have the radius, we can calculate the area of the circular field using the formula:

Area = π * (radius)^2

Where π (pi) is approximately equal to 3.14159.

Area = 3.14159 * (550)^2
Area ≈ 3.14159 * 302500
Area ≈ 950625.985

Rounded to the nearest whole number, the area of the circular field is approximately 950626 square feet.

To find the area of the circular field, we need to first determine the circumference of the fence.

The cost of building the fence is given as Rs 7700 at Rs 14 per foot. This means that the total length of the fence can be found by dividing the cost by the cost per foot:

Length of fence = Rs 7700 / Rs 14 per foot
= 550 feet

Next, we can use the circumference formula for a circle to find the circumference of the field:

Circumference = 2πr

Here, we need to find the radius (r) of the circular field. To do this, we'll divide the length of the fence by 2π (as 2πr is equal to the circumference):

550 feet = 2πr

Solving for r, we have:

r = (550 feet) / (2π)
≈ 87.39 feet

Once we have the radius, we can find the area of the circular field using the formula:

Area = πr²

Plugging in the value of the radius we calculated earlier, we have:

Area = π(87.39 feet)²
≈ 24062.5 square feet

Therefore, the area of the circular field is approximately 24062.5 square feet.

circumference = 7700/14 ft

= 550 ft

since C = 2πr
2πr = 550
r = 275/π

area = π(275/π)^2
= (275^2)/π
= appr 24072.2 ft^2

I waited to do any calculations to the very end, then used π of my calculator.
