Answer 2

Correct Question-:

• The area of a circle whose diameter is 14 cm is __________ ?

AnswEr-:

• $\underline{\boxed{\star{\sf{\purple{Area \:of\:Circle= 154cm² }}}}}$

Explanation-:

Given -:

• The diameter of Circle is 14 cm .

To Find -:

• The area of Circle.

Solution-:

• Radius of Circle = Diameter/2

Here ,

• Diameter of Circle = 14 cm

Now ,

• Radius = 14/2
• Radius = 7 cm

Therefore ,

• Radius of Circle = 7 cm . ________[1]

Now ,

• $\underline{\boxed{\star{\sf{\purple{Area \:of\:Circle=\pi × Radius ² }}}}}$

Here ,

• Radius of Circle = 7 cm ________[From 1]
• π = 22 / 7

Now ,

• Area = 22/7 × 7 × 7
• Area = 22/7 × 7 × 7 Area = 22 × 7
• Area = 22/7 × 7 × 7 Area = 22 × 7 Area = 154 cm²

Hence,

• $\underline{\boxed{\star{\sf{\purple{Area \:of\:Circle= 154cm² }}}}}$
