Answer:
78.5 cm²
Step-by-step explanation:
GIVEN :-
- Diameter of the circle (d) = 10 cm
- π = 3.14
TO FIND :-
FORMULAES TO BE USED IN THIS QUESTION :-
- [tex]Radius = \frac{Diameter}{2}[/tex]
- [tex]Area = \pi \times (Radius)^2[/tex]
SOLUTION :-
[tex]Radius\: (r) = \frac{Diameter}{2} = \frac{10}{2} = 5 cm[/tex]
[tex]=> Area = \pi r^2[/tex]
[tex]= 3.14 \times (5)^2[/tex]
[tex]= 3.14 \times 25[/tex]
[tex]= 78.5 \: cm^2[/tex]
