7x(x+1.8)=0
7x+12.6x=0 (Distributed)
19.6x=0 (Added like terms)
x=0 (Divided 0 by 19.6)
I hope that helps
Hola!
Circumference of circle is 12.56 cm
Means,
2 × π × r = 12.56
r = 12.56 × 3.14 × 2
r = 1.999 cm
According to Question,
Area of Circle:
π × r²
3.14 × 1.99 × 1.99
12.547 cm² = 12.56 cm² (approximately.)
Hence,
Area of Circle is 12.56 cm²
hope it helps!
