Question

find the area of circular garden of radius 42m​

Answer 1

$\Huge{\underline{\underline{\mathfrak{Answer \colon }}}}$

Given,

The radius of the circle is 42m

Let the radius of the circle be r » r = 42 m

Area of a circle is given by

$\huge{ \boxed{ \boxed{ \tt{A = \pi {r}^{2} }}}}$

Now,

$\large{ \sf{A = \frac{22}{7} \times {42}^{2} }} \\ \\ \large{ \leadsto \: \sf{A = \frac{22}{ \cancel{7}} \times \cancel{42} \times 42 }} \\ \\ \large{ \leadsto \: \sf{A = 22 \times 6 \times 42}} \\ \\ \huge{ \leadsto \: \boxed{ \sf{A =5544 \: {m}^{2} }}}$

The area of the circular garden is 5544 m²

Answer 2

Question : Find the area of circular garden of radius 42m.

Solution :

Short form for the following :

• Radius = R
• Area = A

Given :

• Radius of circular garden = 42 m

Now :

$A = \pi {r}^{2} \\ \: \: \: \: = \frac{22}{7} \times 42 \: m \times 42 \: m \\ \: \: \: \: = 22 \times 6 \: m \times 42 \: m \\ \: \: \: \: = 5544 \: {m}^{2}$

Area of circular garden

$= 5544 \: {m}^{2}$
