Question

Please help me i'll mark u as brainly if u give me the correct answers

Answer 1

Answer:

49π cm²

Step-by-step explanation:

Diameter (d) = 14 cm

Radius (r) = d/2 = 14/2 = 7 cm

Area of a circle

= πr²

= π × (7)²

= 49π cm²

Hope it helps ⚜

Answer 2

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
