A farmer has a field in the shape of a semicircle a sketch of the field is shown The farmer ask a builder to raise a fence around the edge of the field he gets the following quotation
Total cost=32.65 per metre of fence+150for each day works
The builder estimates that it will take five days to build the fence work out the total cost

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

8.3 and the 3 is repeating

hope this .
