Information provided with us :

  • Diameter of the given circle is 14 cm.

What we have to calculate :

  • Area of that circle?

Performing Calculations :

Here we would be first calculating the radius of the given circle. As we know that radius of the circle is calculated by the formula,

  • r = d / 2

Putting the values,

=> r = 14 / 2

=> r = 7

Therefore, radius is of 7 cm.

Now, heading up to calculate the area of circle.

Formula,

  • A = πr²

Putting the values in the formula,

=> A = 22/7 (7)²

=> A = (22/7) × 7 × 7

=> A = 22 × 7 × 7 / 7

=> A = 22 × 49 / 7

=> A = 22 × 7

=> A = 154 cm²
