Answer:

A. 31.4 in.

Step-by-step explanation:

Formula for the circumference:

C = dπ (d = 2r)

Therefore:

C = 10π

C = 10 · 3.14

C = 31.4 in.

Answer:

A: 31.4 in

Step-by-step explanation:

Use the equation C = 2πr to solve your problem.

Since you are given the radius <em>r </em>you only need to plug in 5 in. to r and calculate it on the calc. When you multiply everything together you should get 31.4 in.

2. The rectangular floor of a garage has an area of 198 square feet. Andy knows that the floor is 7
Charra [1.4K]

Answer:

length = 18 ft

Step-by-step explanation:

Let w = width

L = w+7

Area = l*w

198 = (w+7) (w)

Distribute

198 = w^2 +7w

Subtract 198 from each side

0 = w^2 +7w -198

Factor

What 2 numbers multiply to -198 and add to 7

18* -11 = -198

18+-11 = 7

0=(w+18) (w-11)

Using the zero product property

w+18 =0  w-11=0

w= -18   w=11

We cannot have negative width  so w=11

We want the length

l = w+7

l = 11+7 = 18

How many hours is 3200 seconds <br><br> 3200 s =_____hrs
dezoksy [38]

Dividing by 3,600

1

Determine the number of seconds you have. This information should be given, or it should be a figure you calculated yourself.

For example, you might be converting 2,400 seconds into hours.

ivide the number of seconds by 3,600. Note that there are 3,600 seconds in one hour.[1] So, if you have more than 3,600 seconds, your conversion will be greater than  hour. If you have less than 3,600 seconds, your conversion will be a fraction of an hour.

3

Convert your decimal to minutes. This step is helpful if you are working with a number of seconds equal to less than an hour, so that you can gauge how long a certain decimal is. To convert the decimal to minutes, multiply it by 60.[2]

3200 seconds = 0.88888889 Hours

(rounded to 8 digits)
