Question

area of circle-dimeter=49 ​

Answer 1

$\huge{\bold{\underline{\underline{Given:-}}}}$

• Diameter of circle = 49cm

$\huge{\bold{\underline{\underline{To\:Find:-}}}}$

• Area of circle

$\huge{\bold{\underline{\underline{Solution:-}}}}$

Diameter = 49 cm

Radius = $\frac{D}{2}$ = $\frac{49}{2}$

$\large{\bold{Area \:of \:circle \:=\: πr²}}$

$= > \frac{ \cancel{22}}{ \cancel {7} } \times \frac{ \cancel {49}}{ \cancel {2}} \times \frac{49}{2}$

$= > \frac{11 \times 7 \times 49}{2}$

$= > \frac{3773}{2}$

$= > {1886.5 \: cm}^{2}$

∴ Area of circle = 1886.5 cm²

Answer 2

Answer:

1886.5 units²

Step-by-step explanation:

Diameter = 49

Thus, radius = diameter/2 => 49/2 => 24.5 units

Area = πr²

=> 22/7*24.5*24.5 => 1886.5 units²

Thus, the area of a circle with a diameter of 49 units is 1884.785 units (I put units as you have not specified the unit to be used).
