Answer:
40° and 9°
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
If the polygon is regular then the measure of each exterior angle is
← where n is the number of sides
(a) for a regular 9 sided polygon
exterior angle =
= 40°
(b) for a regular 40 sided polygon
exterior angle =
= 9°
Let P = Pressure, V = Volume and be K = constant, by definition of Boyle's Law in which says that the volume of a gas varies inversely with the pressure, we have: P = K / V 586 = K / 5 K = 2930. Then, the pressure when the volume is 2L will be: P = 2930/2 = 1465Kpa
19.625cm squared because you have to divide the diameter by 2 to get the radius.
area of circle=pi times radius times radius
=3.14 times 2.5 times 2.5
=19.625cm squared
