4pi = w -6pi
Add the 6pi from both side
W=10pi
Answer: radius = 6.5millimeters; Area = 132.7m²
Step-by-step explanation:
The circumference of a circle = 2πr
The area of a circle = πr²
The circumference of a button is 40.8 millimeters. Then we can get the radius, thus will be:
Circumference = 2πr
40.8 = 2 × 3.14 × r
40.8 = 6.28r
r = 40.8/6.28
r = 6.5
Radius is 6.5 millimeters
Area = πr²
Area = 3.14 × 6.5 × 6.5
Area = 132.7m²
Answer:
Step-by-step explanation:
i) area of circle = 
ii) therefore side of hexagon, 
iii) therefore area of hexagon, 
iv) difference between the two areas in iii) and i)
