Answer: The minimum amount of fence Laura will need is 15.70 ft.

Step-by-step explanation:

Hi, to answer this question we have to find the circumference of the pond.

The formula for the circumference (C) is:

C = π x d

Where "d" is the diameter.

Replacing with the values given:

C = π x 5 =15.70ft

The minimum amount of fence Laura will need is 15.70 ft.

Feel free to ask for more if needed or if you did not understand something.

Answer: 15.707 feet of fence.

Explanation: The formula to find this would be the one you’d use to find circumference, which is: C = 2(Pi)r

Half of the diameter is the radius, so plug that in and it becomes:

C = 2(pi)2.5

Then you just solve it and the result is C = 15.707

After driving 10 miles, in a 1/3 of a day, Mark is trying to figure out how many
svet-max [94.6K]

Answer:

30 miles

Step-by-step explanation:

Let the number of days = d

in 1/3 of a day, or 1/3d, he drove 10 miles

The equation is:

10 = \frac13d

To find out the number of miles driven in one whole day, we can multiply both sides by 3 or setting up a proportion

<h2>Method 1: Multiplying By 3</h2>

10 = 1/3d

10*3 = 1/3d * 3

30 = 1d

30 miles

<h2>Method 2: Proportions</h2>

\frac{10}{1} = \frac13

10*3 = 1*1                 Cross multiply

30 = 1
