Question

Find the area of a Circle whose diameter is 49m.​

Answer 1

Answer:- 1,886.5 m^2


Solution:-

Given:-

Diameter = 49 m
Radius = 24.5 m [ Radius is one half of diameter ]

Area of Circle = pie r^2
=> 22/7 ✖️ (24.5)^2
=> 22/7 ✖️ 600.25
=> 22/7 ✖️ 60025/100
=> 13,20,550/700
=> 13,20,55/70
=> 1,886.5 m^2

Answer 2

Given: Diameter of the circle is 49m.

Need to find: Area of the circle.

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━

★ Firstly, finding the radius of the circle,

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf{Radius=\dfrac{Diameter}{2}}\\\\\\:\implies\sf{Radius=\dfrac{49}{2}}\\\\\\:\implies{\underline{\boxed{\textsf{\textbf{Radius\;=\;24.5\;m}}}}}{\;\bigstar}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\therefore\;{\underline{\sf{Hence,\;the\;radius\;of\;the\;circle\;is\;{\textsf{\textbf{24.5\;m}}}}.}}$

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

★ Now, to calculate the area of a circle formula is given by:

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\star\;\boxed{\pink{\sf{Area\;_{(circle)}=\pi r^2}}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore,

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf{Area=\dfrac{22}{7}\times (24.5)^2}\\\\\\:\implies\sf{Area=\dfrac{22}{7}\times 24.5\times 24.5}\\\\\\:\implies\underline{\boxed{\purple{\frak{Area=1886.5\;m^2}}}}{\;\bigstar}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\therefore\;{\underline{\sf{Hence,\;the\;area\;of\;the\;circle\;is\;{\frak{1886.5\;m^2}}}.}}$
