GOVT.GIRLS.SEC. SCHOOL BUNDALA(JAL)
WEL COME TO THE WORLD OF MATHEMATICS OBJECTIVEs:-1. TO LEARN ABOUT THE AREA OF FIGURES. 2.TO LEARN ABOUT THE AREA OF SALIDS.
FIGURES / SOLIDS
FIGURES RECTANGLE SQUARE TRIANGLE CIRCLE
SOLIDS CUBIOD CUBE RIGHT CIRCULAR CONE SPHERE
AREA OF RECTANGLE A RECTANGLE IS THAT WHOSE LENGTH AND BREADTH ARE DIFFERENT AND ALL ANGLES ARE RIGHT ANGLES. AREA OF RECTANGLE = LENGTH *BREADTH A = L*B
AREA OF SQUARE:- A SQUARE IS THAT WHOSE LENGTH AND BREADTH ARE SAME AND ALL THE ANGLES ARE RIGHT ANGLES. AREA OF SQUARE= SIDE*SIDE
AREA OF TRIANGLE:- A TRIANGLE HAS THREE SIDES AND THREE ANGLES. AREA OF TRIANGLE:-1/2* BASE * HEIGHT.
AREA OF CIRCLE:A CIRCLE IS THE PATH TRACED OUT BY A MOVING POINT WHICH MOVES AT A FIXED DISTANCE FROM A FIXED POINT AREA OF CIRCLE= r2
AREA OF CUBIOD A CUBIOD HAS SIXS FACES EACH FACE IS A RECTANGULAR REGION. THE OPPOSITE FACES ARE CONGURENT. TOTAL SURFACE AREA OF CUBIOD. = 2 (LB+BH+HL)
AREA OF CUBE A CUBE IS LIKE A CUBIOD BUT ITS LENGTH ,BREADTH AND HEIGHT ARE SAME. TOTAL SURFACE AREA OF CUBE= 6(SIDE)2
AREA OF RIGHT CIRCULAR CONE A RIGHT CIRCULAR CONE HAS A CIRCULAR BASE AND ONE EDGE ON A POINT. TOTAL SURFACE AREA OF CUBE= r (L+R)
AREA OF SPHERE A GROUP OF POINTS IN THE REGION FROM A FIXED POINT IS CALLED SPHERE TOTAL SURFACE AREA OF SPHERE= 4 r2
ACKNOWLEDGEMENT THIS PROJECT OF COMPUTER TECHNOLOGY IS VERY USEFUL IN THE FIELD OF EDUCATION IN OUR SCHOOL A LOT OF THANKS TO OUR INSTRUCTOR MISS. DOLLY BAGGA and MR.KAMAL RAJ WHO GUIDE US VERY POLITELY.
