The area of a circle equals pi x r squared
or
A = pi x r2
A = area of circle
pi = approximatley 3.14
r = radius
effectiveness of a fin is the rate of heat transfered by the fin to the rate of heat transfered without the fin.By knowing the effectiveness we can determine how a fin increases the heat transfer rate when compared to the normal surface without a fin.Whereas by determining the efficiency of a fin we can know the heat transfering capacity of the fin material. both are ratio to heat transfer by fin but, in effectiveness we take base area of fin, other hand in fin efficiency we choose fin area except base area or area which contact with surrounding.
No, a dorsal fin from a fish is on its back area.
Area of a circle = pi*radius2
Area of a circle = Pi * radius2
Area of a circle = pi*radius2
The area of a circle is the amount of space inside the circle. The area of a circle is calculated by multiplying pi(3.14159) by the radius squared.
Area of a circle is calculated by A=2*p*r where A represents the circle's area and r is the radius of the circle.
Using 3.14 as Pi the area of circle is: 0
the area of the circle is increased by 400%
The circle's area is 70,900,000 square units.
Area of any circle = pi*radius2
Area of a sector of a circle.
