Answer:

Area= 616sq.cm

perimeter = 88 cm

Step-by-step explanation:

Area of the circle = πr^{2} = 22/7 * 14 *14 = 616 sq.cm

Perimeter = circumference = 2πr = 2 * 22/7 * 14 =88cm

Answer:

Area : 616 cm²

Perimeter (Circumference) : 88 cm

Solution :-

Given :-

  • Radius = 14 cm

Solution :

Given : Radius = 14cm

Area of the circle = πr²

➪ Area of circle = π (\frac{22}{7}\\) × radius × radius

➪ Area of circle = π (\frac{22}{7}\\) × 14 × 14 cm²

                           = 616 cm²

___________________________________

Given : Radius = 14cm

Perimeter of the circle =    

➪2 × π (\frac{22}{7}) × radius

➪2 ×  \frac{22}{7} × 14 cm

\frac{44}{7} × 14

➪44 × 2

➪88 cm

Remember !

  • Perimeter of circle is = (P = 2πr)

Here, R is the radius of the circle.

  • Area of the circle is = (A = π r²).

Here, R is the radius of the circle
