Answer :
Answer: 258.31 cm²
Here it's given that ,
- Circumference of the circle = 57cm.
To Find ,
- The area of the circle.
We know that ,
→ Circumference = 2πr
Substituting the respective value ,
→ 57cm = 2πr
→ r = 57cm/2π
→ r = 57/(2*3.14) cm
→ r = 9.07 cm
And ,
→ Area = πr²
→ Area = 3.14 * (9.07cm)²
→ Area = 3.14 * 82.26 cm²
→ Area = 258.31 cm²
Hence the area of the circle is 258.31 cm²
I hope this helps.
Step-by-step explanation:
Given :-
- Circumference of circle = 57cm
To find :-
- area of circle
Solution :-
Circumference of circle = 57cm
2πr = 57cm
2×3.14×r = 57cm
r = 57/6.28 cm
r = 9.07cm
area of circle = πr²
Area = 3.14×9.07² cm²
Area = 258.31 cm²
