Diameter = 49 cm
Radius = [tex]\frac{D}{2}[/tex] = [tex]\frac{49}{2}[/tex]
[tex]\large{\bold{Area \:of \:circle \:=\: πr²}}[/tex]
[tex] = > \frac{ \cancel{22}}{ \cancel {7} } \times \frac{ \cancel {49}}{ \cancel {2}} \times \frac{49}{2} [/tex]
[tex] = > \frac{11 \times 7 \times 49}{2} [/tex]
[tex] = > \frac{3773}{2} [/tex]
[tex] = > {1886.5 \: cm}^{2} [/tex]
∴ Area of circle = 1886.5 cm²
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).
