Question

Find the circumference of the inner and outer circle, shown in the given figure. (Take π = 3.14)

pls give the explanation I will mark you as brainliest ​

Answer 1

Circumference of inner circle

r = 12.5 - 8.5 m

r = 4 m

$\pi{r}^{2}$

$3.14 \times {4}^{2}$

$3.14\times 16$

$50.24 \: {m}^{2}$

Circumference of outer circle

r = 12.5 m

$\pi {r}^{2}$

$3.14 \times {12.5}^{2}$

$3.14 \times 156.25$

$490.625 \: {m}^{2}$
