Answer:
<em>Area = 254.34 inches ³</em>
Step-by-step explanation:
The formula to find the surface area of a sphere is:
To find the volume of the sphere, we first need to figure out the radius (
) of the sphere. We can accomplish this by reversing the formula that was used to find the surface area. 
Divide both sides by pi (
).
Divide both sides by 4.
Find the square root of both sides.
<em>radius = 9</em>
<em />
Insert the value of the radius into the formula for finding the volume of a sphere. 
<em>Area = 254.34 inches ³</em>
<em />

Step-by-step explanation:
Hello!
1.
find circumferece
c=2pir
c=2*6*pi=12pi
intercept is 5.4
2pi radians=all
part/whole=part/whole
5.4/12pi=x/2pi
times both sides by 12pi
5.4=6x
divide both sides by 6
0.9=x
answer is 0.9 radians
2.
assuming 9pi/5 radians
find circumference
c=2pir
c=2*26.9*pi
c=53.8pi
arc/circumference=(9pi/5)/2pi
x/(53.8pi)=(9pi/5)/(2pi)
x/(53.8pi)=18/5
times both sides by 53.8pi
x=608.46266 m
about x=608.46 m
Hope this Helps! Have A Wonderful Day! :)
