Given:
The diameter of a circle = 20 feet
To find:
The exact circumference of the circle.
Solution:
We know that the radius is half of the diameter of the circle.
The diameter of a circle is 20 feet. So, the radius of the circle is 10 feet.
The circumference of the circle is:
Where, r is the radius.
Substituting , we get
Therefore, the exact circumference of the circle is 62.8 feet.
Note: All options are incorrect.
Answer:
Yes
Step-by-step explanation:
First, we need to put them in the same terms.
30/60... 30 is half of 60 so it can be simplified to be written as 1/2, 2/4, 4/8, or 5/10.
5/10 is smaller than 9/10
9/10 is bigger than 5/10
9/10 is bigger than 30/60
Answer:
slope= -1.5
Step-by-step explanation:
-6/4= -1.5
Answer:
1. 60 // It can be found between whole numbers 63 and 65.
2. 10 // It can be found between whole numbers 6 and 8.
3. 20 // It can be found between whole numbers 18 and 20.
