Question

if radius of the big circle is double of a small circle than the area of a big circle is of the small circle

​

Answer 1

Answer:

If radius of the big circle is double of a small circle than the area of a big circle is double of the small circle  

Step-by-step explanation:

example

radius of small circle be 7 cm

so, radius of big circle will be 14 cm

area of small circle = 2πr

                              = 2 × $\frac{22}{7}$ × 7

                              = 44 $cm^{2}$

area of big circle = 2πr

                            = 2 × $\frac{22}{7}$ × 14

                            = 88 $cm^{2}$
