  • Look at this rectangle. Find the value of p.
    p+2+p+2 =14                         2p+4=14     2p=10        p=5
  • The diameter of a circle is 6 centimetres. What is the circle's area?
     ≈28.26
  • What is HI?
    Radius
  • What is pi "("π")
    Pi ("π") is the ratio of the circumference of a circle to its diameter.
  • Find the missing side lengths.
    49.8=x*6                                           x=49.8 / 6                                    x=8.3cm
  • What is Perimeter ?
    Perimeter is the total length of the sides of a two-dimensional shape
  • Find the value of y.
    y=11+14 =25          y=51-25=26           y =26 : 2                                             y=13
  • What is UV?
    Chord
  • The diameter of a circle is 18 feet. What is the circle's radius?
    d =2r     18 =2r   18÷2 =r     9 =r
  • What is the diameter ?
    Is the length of a line passing through the centre from one point on the circle to another.
  • What is Area ?
    The size of a surface. The amount of space inside the boundary of a flat (2-dimensional) object .
  • Find the missing side length:
    Remember(b*h),so          43.5=b*5                                        b=8.7cm
  • Look at this square. Find the value of w.
    =w+w+w+w =24                                =4w =24                                                w =6
  • Find area of the circle :
    A=3.14* 7.1 *7.1                                  A=3.14* 50.41                       A=158.2874 ~ 158.29 ( 2d.p)
  • What is the area?
    Area=1/ 2 × base × height            A=1 2 × 21 × 14                                           A = 147
  • Find the area of the shaded part:
    75.36cm2
