Area of sphere is given by:
Area=4πr²
but:
r=3 inches
thus
Area=4×π×3²
Area=36 π in²
Answer: 36π sq. in
Answer: 4.4
Step-by-step explanation:
The formula for calculating the area of regular hexagon is given as :
Area = 

Where a is the length of a side.
Substituting the value given , we have :
50 = 

50 x 2 =

100 =

Divide through by 
= 
= 19.24500897
Take the square root of both sides :
a = 
a = 4.3869
To the nearest tenth
a = 4.4
A + b
47 + 31
78
a= 47
b = 31
