I set it up as a ratio with hours on the top and the fraction of the job on the bottom.  It looks like this: 5/(2/3) / x/1, because 1 is the whole job if 2/3 is only a fraction of it.  Cross multiplying gives you 2/3x = 5. Solving for x gives you that it will take 7.5 hours to complete a whole job if it takes 5 hours to complete 2/3 of it.

Which statements are true about the circle shown?
CaHeK987 [17]

Answer:

Among the five statements,statement 1 and 4 are true for the circle shown.

Step-by-step explanation:

Given:

An image is attached here.

A circle with radius = 15.4 m

We ave to find the diameter,circumference and relationship between the two.

Formula to be used:

⇒ Diameter of a circle = 2r        

⇒ Circumference = 2πr

Lets find the values.

  • Diameter = 2r=2(15.4) = 30.8 m
  • Circumference = 2\pi r =2(3.14)(15.4)=96.7 m
  • Relationship = \frac{circumference}{diameter} = \frac{96.7}{6} =3.1

We can say that a little more than 3 diameters could be wrapped around the circle.

From the drop down our choices are.

  • The diameter of the circle is 30.8 m.
  • The approximate circumference of the circle ,rounded to the nearest tenth is 96.7 m.

Option 1 and 4 are the right choices.
