Question

2. Find the area of the following circles, given that:


(b) Diameter = 49 m​

Answer 1

Answer:

1,886.5 m²

Step-by-step explanation:

$radius \: = \frac{diameter}{2}$

radius = 49/2

= 24.5

Area= πr²

$= \frac{22}{7} \times 24.5 \times 24.5$

= 1,886.5 m²

Therefore, Area of the circle is 1,886.5 m²

Answer 2

Answer:

Given :-

• Diameter (d) = 49 m
• radius = 49/2 m

To find :-

• Area of circle

Using formula :-

• area of circle = πr²

Solution :-

$\longrightarrow \mathcal{ \red{area = \pi {r}^{2} }}$

$\longrightarrow \mathcal{ \blue{ \frac{22}{7} \times \frac{49}{2} \times \frac{49}{2} }}$

$\longrightarrow \underline{\boxed{\mathcal{ \green{ 1886.5 \: {m}^{2} }}}}$

Hence the area of circle is 1886.5m²
