Answer:
b
Step-by-step explanation:
Amount that trouvaughn paid : $0.80b
ten dollar bill = $10
so $(10-0.80b)
We know that
the axis is equal to the diameter of a sphere
so
D=14 units
r=D/2-----> r=7 units
<span>the surface area of the sphere=4*pi*r</span>²------> 4*pi*7²=196*pi units²
the answer is the option
<span>C. 196 pi units^2</span>
The answer has to be 144 since it is the only one smaller than 180
1 and 11/12 hours I think
