The perimeter of a circle is its total circumference, but in this case a semi-circle will measure half the circumference plus its diameter.
If the semicircle measures 8cm then the total circle is 16 cm, and we can calculate its diameter or radius from there. The perimeter is defined as:
p = pi*diameter = 16
diameter = 16/pi = 16/3.14
diameter = 5.1 cm
Therefore the semi-circle perimeter is:
perimeter = semi-circle + diameter = 8 + 5.1 = 13.1 cm
1/3 ÷ 2 =
1/3 x 2/1. you do this by doing the reciprocal of 2, and then you do KCF ( keep, change, flip,)
keep 1/3 change ÷ to × and flip 2/1 to 1/2.
1/3 x 1/2 = 1/6.
hopefully this helps you

Answer: How do you find the rate of change of volume?
The rate of change in volume is dV/dt. The question is asking for the rate that the side length is changing. That would be ds/dt. If we take the derivative of both sides of V = s^3 with respect to time, we get dV/dt = d/dt[s^3].
