Question

area of circle ............​

Answer 1

• Area of circle = πr²
• Area of rectangle = length × breadth
• Area of square = side × side
• Perimeter of rectangle = 2(length + breadth)
• Perimeter of square = 4 × side
• Area of Rhombus = ½ × product of diagonals
• Area of Parallelogram = base × height
• Perimeter of circle = circumference of circle = 2πr
• Total surface area of cuboid = 2(lb + bh + lh)
• Curved surface area of cuboid = 2(l + b)h
• Volume of cuboid = length × breadth × height
• Total surface area of cube = 6a²
• Curved surface area of cube = 4a²
• Volume of cube = a³
