Question

3 Find the Area of a circle whose radius is 224 mm​

Answer 1

Step-by-step explanation:

Area of circle=

$\pi {r}^{2} = \frac{22}{7} \times 224 \times 224$

$= 14336 \: {mm}^{2}$

Answer 2

✫ The area of circle is 1,57,696 mm² ✫

Step-by-step explanation:

Given: Radius of circle is 224 mm.

To find: Area of circle

Required Formula:

• Area of circle = πr²

Where,

• r (radius) = 224
• A = Area of circle

Putting the values,

$\\ \longmapsto \: \sf{A = \pi \times {(224)}^{2} } \\ \\ \longmapsto \: \sf{A =\pi \times 224 \times 224 } \\ \\ \longmapsto \: \sf{A =\pi \times 50176 } \\ \\ \longmapsto \: \sf{A = \frac{22}{ \cancel{7}} \times \cancel{ 50176}} \\ \\ \longmapsto \: \sf{A =22 \times 7168 } \\ \\ \longmapsto \: \underline{ \boxed{\frak{A = 157696 \: {mm}^{2}}}} \: \green{ \bigstar}$

• Hence,The area of circle is 157696 mm².
