Question

find the area of a loop whose diametre is 28 cm take π as 22÷7​

Answer 1

Answer:

Diameter = 28 cm

So, radius = 28/2 cm

= 14 cm

So,

Area

$\pi {r}^{2}$

= 22/7 * 14 * 14 cm^2

= 616 cm^2

Hope it helps...!!

Answer 2

$\red{\bold {\underline {\underline {\star \: {Given}}}}}$

$\longrightarrow \pi = \frac{22}{7}$

$\longrightarrow \: Diameter.$

$\red{\bold {\underline {\underline {\star \: {Solution}}}}}$

$area \: of \: loop \: = \pi {r}^{2} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \longrightarrow \: \frac{22}{ \cancel7} \times 14 \times \cancel1 \cancel4 . \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \longrightarrow \: 22 \times 14 \times 2. \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \longrightarrow \: 616 \: {cm}^{2} .$
