A design on the window of a building. The curved part XY is an arc of a circle. The rise of the segmental arc is 10cm it's span is 100cm and ZX=ZY=120cm calculate taking π to be 22/7 where necessary A radius of the circle The area of the segmental correct to 2s. F The total area of the design correct to 3s. F

J= r + 9 because since jessica rode 9 more miles than roger, you add 9 miles to rogers mileage.

In  mathematics, the  pythagorean theorem, also known as  pythagoras' theorem, is a fundamental relation in  euclidean geometryamong the three sides of a  right triangle. it states that the square of the  hypotenuse  (the side opposite the  right angle) is equal to the sum of the squares of the  other two sides. the  theorem  can be written as an  equationrelating the lengths of the sides  a,  b  and  c, often called the "pythagorean equation".
