It's answer is option A.
As the area of circle is given which is 58 square feet, we are to find circumference of the circle.
We know that area = π r^2
Where π = 3.14 and r is radius of the circle
So it will become
3.14 x r^2 = 58
r^2 = 58/3.14
r^2 = 18.4713375796
If we take square root of both sides, we get
r = 4.297829403268585 feet
By using this value of r we can find circumference of the circle,
As,
Circumference = 2 π r
It will become
2 x 3.14 x 4.297829403268585
26.99036
Which is very close to the option A.
Answer:
Sabrina necesito 8 horas para llegar a su casa mientras que Diana necesito solo 3.4 horas.
Step-by-step explanation:
debemos resolver la siguientes equaciones:
A + B = 11.4
65A + 50B = 690
donde:
A = tiempo que le toma a Sabrina llegar a su casa
B = tiempo que le toma a Diana llegar a su casa
A = 11.4 - B
65 (11.4 - B) + 50B = 690
741 - 65B + 50B = 690
741 - 690 = 65B - 50B
51 = 15B
B = 51 / 15 = 3.4 horas
A = 11.4 - 3.4 = 8 horas
