Question

what what is the formula of area




​

Answer 1

Answer:

kiska area like triangle,squre

Answer 2

Answer:

Step-by-step explanation:

Square=side^2

Rectangle=length × width

Parallelogram=base × height

Triangle=base × height / 2

Regular n-polygon=(1/4) × n × side^2 × cot(pi/n)

Trapezoid=height × (base1 + base2) / 2

Circle=pi × radius^2

Ellipse=pi × radius1 × radius^2

Cube (surface)=6 × side^2

Sphere (surface)=4 × pi × radius^2

Cylinder (surface of side)=perimeter of circle × height

                                           2 × pi × radius × height

Cylinder (whole surface)=Areas of top and bottom circles + Area of the side

                                          2(pi × radius^2) + 2 × pi × radius × height

Cone (surface)=pi × radius × side

Torus (surface)=pi^2 × (radius2^2 - radius1^2)
