anonymous · Answer

The field area can also be found by adding the area of the circle to the rectangle's area.

anonymous · Answer

try again..!!!its not accurate..

anonymous · Answer

Ok But do I use the area of the rectangle as R?

anonymous · Answer

I am so confused now.

anonymous · Answer

$$\pi  \left(\frac{49}{2}\right)^2+49\text{*}  95=6541 \text{ rounded} $$

anonymous · Answer

Oh THANKYOU THANKYOU~!!!!

anonymous · Answer

Your welcome.

anonymous · Answer

But Now what do I need to do?

anonymous · Answer

yes..now you have given that 0.08 dollar per sq.yd is expenditure..now just multiply the area with 0.08 to find total xpenditures for whole field..you will get result.

anonymous · Answer

Ok Now I get it So the answer is $523.18

anonymous · Answer

So for the formula$$\pi * SemiCircLength \div NumberOfCemiCircles + SemiCircLength * SizeOfSquare = Answer$$

anonymous · Answer

no...$${\pi*(semi circle lenght)^2}/2+{\pi*(semi circle lenght)^2}/2+ area of rectangle$$
