Hoods become necessary any time water temperatures drop below: 20°C/68°F.
<h3>Why is it necessary to use
Hoods any time
water temperatures drop below:
20°C/68°F?</h3>
It is important to use hood so as to adjust the cold temperature, so as to be able to gain heat.
Therefore, hood serves as a covering for the head as well as the neck which has a opening face that prevent cold.

Answer:
14
Explanation:
A=pi × r²
153.86 = 3.14 × r²
Divide both sides of the equation by 3.14
it becomes:
r²=153.86÷3.14
r²=49
taking the square root for both sides of the equation
r = 7
and
diameter = 2 × radius
diameter = 2 × 7 = 14
The triangle has a 60° angle, and the two adjacent sides are 12 and "12 times the square root of 3".
So, the area of the triangle, Δ = sq. units.
Now, we have to find the radius of the circle with the same vertex as a center, if the arc in the triangle bisects the area of the triangle.
So, if the radius of the circle is r units, then
⇒ 0.5238 r² = 54
⇒ r² = 103.092
<u>⇒ r = 10.15 units. (Answer)</u>
