Question

Area of circle is 24.64 sq m find radius

Answer 1

Area of the circle is given as 24.64 m²

We already know that :-

The area of a circle is equal to :-

$\pi {r}^{2}$

Now,

Applying the formula :-

$\pi {r}^{2} = 24.64 \\ \\ \\ \\ = {r}^{2} = \frac{24.64 \times 7}{22} \\ \\ \\ \\ {r}^{2} = 1.12 \times 7 \\ \\ \\r = \sqrt{ \frac{112 \times 7}{100} } \\ \\ \\r = \frac{4 \times 7}{10} \\ \\ \\ \\r = 2.8 \: m$

Therefore,

The radius of the circle is equal to 2.8 metres.

Hence ,

Solved!

Answer 2

Answer....

πr 2=24.64

=r 2

= 22

24.64×7

r 2 =1.12×7

r= 100

112×7

r= 104×7

r=2.8m

hope it helps
