Answer:
Perimeter = 42 units Area = 57.73 square units
Step-by-step explanation:
Perimeter of an Astroid = 6l ---> 6 x 7 = 42 units
Area of an Astroid = (3 x pi x a^2)/8 = 57.73 square units
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)
Answer:

Step-by-step explanation:
Recall that
.
Therefore,
.
We have to add 8/15 to 2/5.
To add two fractions we have to make them have the same denominator, so we have to convert 2/5 to have a denominator of 15. To do this, we have to multiply 2/5 by 3 and then we can add the fractions:

Answer: 14/15
