Answer:
Option C. 
Step-by-step explanation:
we know that
In the right triangle ABC
The tangent of angle B is equal to the opposite side angle B divided by the adjacent side angle B
substitute the values
5a^3 + 3b^4
insert the numbers into the equation.
5(4)^3 + 3(-5)^4
evaluate
5(64) + 3(625)
evaluate
320 + 1875
the solution is:
2195
A cell has a radius: r = 3 nmThe surface area of a cell:A = 4 r² π = 4 · 3² π = 4 · 9 π = 36 π nm²The volume of a cell:V = 4/3 r³ π = 4/3 · 3³ π = 4 · 9 π = 36 π nm³Answer: The surface area is 36 π nm² and the volume is 36 π nm³.
Distance travelled must be equal to fuel conserved in travelling per litre
distance=9 1/2*25.2
=19/2*25.2
=239.4 miles
