Answer:
56.6mm
Step-by-step explanation:
Take the radius and double it to get the diameter
9mm * 2 = 18mm
Multiply the diameter by pi to get the circumference of the circle
18mm * 3.1415 = 56.547mm
Answer:
96 feet
Step-by-step explanation:
Given : A square garden has a diagonal of 34 ft. Colton wants to put a fence around the entire garden.
To Find: How much fencing will he need? Round to the nearest foot.
Solution:
Formula of diagonal of square = 
Where a is the side of the square.
Since we are given the diagonal length of square garden = 34 ft.
So, 


Thus the side of the square garden is 24.04 ft.
Now we are supposed to find how much fencing is required
So, we are supposed to find the perimeter of square.
Perimeter of square = 
= 
= 
Thus he need 96.16 ≈ 96 feet fencing .
He is correct but he might be doughting him self

Step-by-step explanation:
Let x represent the smallest angle. Then the largest is 3x, and the remaining angle is 180-4x. The problem statement tells us
.. 3x > 180 -4x > x
Adding 4x gives us
.. 7x > 180 > 5x
or
.. 36 > x > 180/7 = 25 5/7
The angles, smallest to largest, are
.. x, 4(45 -x), 3x
where 25 5/7 < x < 36
The angles could be, for example, any of ...
.. 26°, 76°, 78°
.. 30°, 60°, 90°
.. 32°, 52°, 96°
.. 35°, 40°, 105°
and an infinite number of other possibilities.
