Question

Find out area of circle having radius 28 cm .​

Answer 1

$\huge \mathbb{ \red {★᭄ꦿ᭄2} \pink{4}\purple{6} \blue {4} \orange{cm} \green{²★᭄ꦿ᭄}}$

Step-by-step explanation:

$\huge\colorbox{orange}{Area of circle =πr 2}$

$\Large{\textsf{\textbf{\underline{\underline{Given r=28 cm\::}}}}}$

$\Huge\large\boxed { π(28)× ²}$

${ \large{ \red{ \underline{ \pmb{ \frak{= 22/7 ×784}}}}}}$

${\mathbb{\colorbox {orange} {\boxed{\boxed{\boxed{\boxed{\boxed{\colorbox {lime}{\boxed{\boxed{\boxed{\boxed{\boxed{\colorbox {aqua} {Answer:- =2464 cm ²}}}}}}}}}}}}}}}$

$\huge\pink{\boxed{\green{\mathcal{\overbrace{\underbrace{\fcolorbox{Black}{aqua}{\underline{\pink{✩Hope it's helps you ✩}}}}}}}}}$

Answer 2

Answer:

Hence, area of the circle having radius 28 cm will be 2464 sq. cm

Step-by-step explanation:

In context to question asked,

We have to determine the area of the circle.

As per question,

We have,

Radius of circle = 28 cm

As we know that,

Radius of circle is the straight line which are drawn from the centre of circle to the circumference of the circle.

As we know that,

Area of circle $=\Pi r^2$

So, for determining the area of circle, we will put the value of radius of circle in above formula,

Thus we will get,

$Area = \Pi r^2\\=>Area = \frac{22}{7} \times 28 \times 28\\=>22 \times 28 \times 4\\=>2464\:cm^2$
