Answer:
n = 5
Step-by-step explanation:
Answer: and agenda:
n = 5
a = 3.96148 m
r = 2.72625 m
R = 3.36984 m
A = 27 m^2
P = 19.8074 m
x = 108 °
y = 72 °
_________________________________
where as r = inradius (apothem)
R = circumradius
a = side length
n = number of sides
x = interior angle
y = exterior angle
A = area
P = perimeter
π = pi = 3.14159...
√ = square root
Side Length a
a = 2r tan(π/n) = 2R sin(π/n)
Inradius r
r = (1/2)a cot(π/n) = R cos(π/n)
Circumradius R
R = (1/2) a csc(π/n) = r sec(π/n)
Area A
A = (1/4)na^2 cot(π/n) = nr^2 tan(π/n)
Perimeter P
P = na
Interior Angle x
x = ((n-2)π / n) radians = (((n-2)/n) x 180° ) degrees
Exterior Angle y
y = (2π / n) radians = (360° / n) degrees
polygon interior and exterior angles
Answer:
Volume increasing rate = 
Explanation:
We rate of change of radius of sphere, 
Diameter of sphere = 100 mm
Radius of sphere = 50 mm
Volume of sphere, V = 
Rate of change of volume = 

Substituting known values

Volume increasing rate = 
Answer:
2,
Step-by-step explanation:
The vertex is the very highest or very lowest point. X coordinates are listed first, then Y.
Step-by-step explanation:
cubing both sides (p+1)^3= (7)^3
=> p^3+1/p^3+ 3(p+1/p) = 343
=> p^3+ 1/p^3 + 3(7)= 343
=> p^3+1/p^3= 343-21
=> p^3+1/p^3= 322
