There must be a relationship (formula) between the lengths of the sides of a Right Triangle and the angles opposite these sides. Help Please. Mike. Look at the law os sines or cosines. Law of sines a/sin(A) = b/sin(B) = c/sin(C) Law of cosines a2 = b2 + c2 - 2bc cos(A) b2 = c2...

I got a different answer for Part a. I first figured the area of the complete circle [A = pi(r^2)]. Then I found one fourth of the complete area. For Part b, you first need the total circumference of the circle. Using the formula C = pi (2r), I get 18.8496 cm. One "side" of ...

Plse tell me if there is any relation between area and perimeter of any regular polygan , if the answer is yes. Can it be applicable to irregular ones also

One idea: I know that a square is the largest area. If you have a perimeter of 16 it would be best to make each side 4 if you want the largest area.

A circular pond has a 95cm wide foot path along the edge.A man walks around theouter edge of te footpath of 55cm long steps.In 640 steps he makes a full round.What is the radius of the pond
Sunday, March 3, 2013 at 12:49pm by Anonymous
640 steps x 55 cm/step = the circumference of the outer edge of the circle. Circumference = 2 times pi times radius. The radius of the outer circle that the man walked, it 95 + r This includes the radius of the inner circle called "r" C = 2 times 3.14 times (95+r) Fill-in the ...

A Rectangular field 750m long and 450m broad has in the middle of it , road 5m wide running at right angles to each other , one long the length and the other along the breadth . Find the area of the path
Wednesday, March 6, 2013 at 7:16am by anoynomous
the area of the path that is running along the breath is= 450*5=2250 m^2 the area of the path that is running along the length is= 750*5=3750 m^2 but as the two roads cross each other in the middle if we just sum the two areas it would over-estimate the crossing area. so to ...
