A field is to be fertilized at a cost of 8 cent per square yard. The rectangle part of the field is 95 yrds long and the diameter of 2 semicircles is 49 yrds. What is the cost of fertilizing it?

So you have a rectangular field with the two ends semicircles?
The rectangular area is 95 yards by 49 yards = 4655 square yards The circular part is pi x diameter squared /4 = 3.14x49x49/4 = 1884.785 sq yds
Total area is 1884.785 + 4655 = 6539.785 sq yds
At cost of 0.08 per sq yd that is .08 x 6539.785 = $523.18

Where is the width and diameter of a rectangle?
A rectangle is an elongated square. It doesn't have a diameter; only circles have diameters.
Does a rectangle have diameter?
NO!!! Diameter refer to circles. A rectamgle has a DIAGONAL.
How do you work out the diameter of a rectangle?
The diameter of a rectangle is the same as its diagonal (angle in a semicircle is a right angle). So the diagonal forms a right angled triangle with the diagonal as the hypotenuse and two sides of the rectangle (a length and a breadth) forming the legs of the triangle. If the lengths of the sides of the rectangle are known, a simple application of Pythagoras's theorem given the measure of the diagonal.
How do you derive of surface area of cylinder?
The surface area of a cylinder can be derived from the area of rectangle. If you 'unroll' a cylinder you have a shape of a rectangle, similar to a sheet of paper. The width of the rectangle will be the height of the cylinder and the length of the rectangle will be the circumference of the cylinder end.So, Area = length * widthwhere, width = height of cylinder & length = circumference of cylinder end = PI*(Diameter of cylinder)Therefore,surface area of a cylinder = (PI)*(diameter of cylinder)*(height of cylinder)Hope that helps!
What is the dimension of a rectangle of 14 units?
The question cannot be answered. First, there is no information as to which measure of the rectangle is 14 units: a diameter, the perimeter, the area. Second, the answer to the question above does not provide sufficient information to answer the question.
What divides a circle into two semicircles?
Its diameter
What is a semicircles radius?
The radius is half the diameter.
What line divides a circle into 2 semicircles?
The circle's diameter
How are the diameter and a semicircle related?
The diameter in the line through the circle that defines the 2 semicircles created.
If the diameter of circle divides it into ---------- semicicrle?
It would divide the circle into two semicircles.
What shape is created when a circle is folded along the diameter?
When a circle is folded along its diameter, it creates two congruent halves or semicircles.
Where is the width and diameter of a rectangle?
A rectangle is an elongated square. It doesn't have a diameter; only circles have diameters.
How do you calculate the diameter of a rectangle?
A rectangle does not have a diameter, as such, but the diagonal is similar enough. If the sides of a rectangle are x cm and y cm then, using Pythagoras's theorem, the diagonal is sqrt(x2 + y2) cm.
What is the answer to finding the area of 4 semi-circles with the diameter of 10 centimeters?
-6
Can you fit a rectangle 21.5x 24 in a 27 diameter circle?
No. The diagonal of the rectangle is a little over 32.2, and nothing that long can fit into a circle with a diameter of 27.
Is it possible to circumscribe a 90 degree angle rectangle?
Yes and the diameter of the circle will be the diagonal of the rectangle.
What is the diameter of a 120mm x 330mm rectangle?
A rectangle does not have a diameter but it has diagonals. So using Pythagoras' theorem each diagonal is about 351.141mm in length rounded to 3 decimal places.
