Before doing the question we shall know that , the area and circumference of a circle with radius 'r units' is given by :-

[tex]{\boxed{\sf Circumference = 2\pi r \:\:units}}[/tex]

[tex]{\boxed{\sf Area = \pi {r}^2 \:\: sq. \: unit}}[/tex]

__________________________

Now coming back on the question ;

[tex]{: \implies \quad \sf Circumference = 2\times \dfrac{22}{7}\times 6}[/tex]

[tex]{\boxed{ \bf \therefore \quad Circumference = \dfrac{264}{7} \: units }}[/tex]

Also ;

[tex]{: \implies \quad \sf Area = \dfrac{22}{7} \times 6 \times 6}[/tex]

[tex]{\boxed{ \bf \therefore \quad Area = \dfrac{792}{7} \: sq. \: unit }}[/tex]

We are done :D

Required solution :

Area of the circle :-

We know formula of calculating the area of circle,

  • A = πr²

Here in this formula,

  • Value of π is 22/7
  • r is radius
  • A is area

We have :

  • Radius (r) = 6 cm
  • Area = ?

Putting the values in the formula,

=> A = (22/7) (6)²

=> A = (22/7) × 6 × 6

=> A = 22 × 6 × 6 / 7

=> A = 22 × 36 / 7

=> A = 792 / 7

=> A = 113.14

Therefore, area of the circle is of 113.14 cm².

Circumference of circle :-

We know that formula of calculating the circumference of circle,

  • C = 2πr

Here in this formula,

  • C is circumference
  • Value of π is 22/7
  • r is radius

We have :

  • Radius = 6 cm

Putting the values in the formula,

=> C = 2 × 22/7 × 6

=> C = 44 × 6 / 7

=> C = 264 / 7

=> C = 37.71

Therefore, circumference of circle is of 37.71 cm.
