Answer 1

Good Question ! This needs a high analysing power to understand the given question.

Answer:

r = 252cm

Step-by-step explanation:

An angular diameter is the describing measurement of an object telling about how large a sphere appears from a particular point.

Now,

$\sf {Given \: that \: angular \: diameter \: ( \theta) = 30 ^{ \circ} }$

Assuming the distance between moon and coin be r.

Arc of coin, OA = 2.2cm

$\sf { \theta \: = \: \dfrac{arc}{radius} }$

$\sf{ \red \implies \: r = \dfrac{2.2 \times 360}{\pi} }$

$\implies \sf{r = \dfrac{2.2 \times 360}{ \frac{22}{7} } }$

$\implies \: r = \frac{2.2 \times 360 \times 7}{22}$

$\implies \sf{r = 7 \times 36}$

$\implies \: \red{{\boxed {\huge \bold{r =252cm }}}}$
