Answer 2

Answer:

Given:-

• Circumference of semi circle = 28.26cm

Find:-

• Radius of semi circle??

Solution:-

Circumference of semi circle = 28.26cm

We know that ⤵

${ \boxed{ \sf{Circumference \: of \: semi circle = \pi \: r}}}$

${ \to{ \sf{28.26 = \frac{22}{7} \times r}}}$

${ \to{ \sf{28.26 = \frac{22}{7} r}}}$

${ \to{ \sf{28.26 \times 7 = 22r}}}$

${ \to{ \sf{197.82 = 22r}}}$

${ \to{ \sf{r = \frac{197.82}{22} }}}$

${ \to{ \sf{r = 8.99 = 9}}}$

↪Therefore, radius of semi circle is 9 cm

Step-by-step explanation:

Verification:-

Circumference = πr

28.26 = 22/7×9

28.26 = 198/7

28.26 = 198/7

28.26 = 28.26

Hence proved ✔
